酸化反応が起きるには過マンガン酸や二クロム酸カリウムを加えないといけないと思ったのですがABCの物質が空気中で酸化されているのは何故でしょうか? また、酸素で酸化できるとした場合Dがカルボン酸にならないのは何故ですか? 教えて頂きたいです。よろしくお願いいたします。

分子式 CHO で示される芳香族化合物には,十数個の異性体が考えられる。そのうち,カ ルボニル基をもつ化合物には5個の構造異性体があり,これらを A,B,C,D,Eとする。A, B, Cは空気中の酸素によって酸化され、それぞれ酸性の化合物F,G,Hとなる。 これらは過 マンガン酸カリウムによってさらに酸化されて,いずれも分子式 CgH6O4 の化合物となる。そ のうち,Fの酸化生成物は加熱すると容易に酸無水物となる。 また, Gの酸化生成物はポリエ ステル繊維の原料の一つとしてよく用いられる。有動を本分 ) 化合物 D, E を還元すると,それぞれ同じ 官能基をもつ化合物I, J となる。 (b, Dはアンモ ニア性硝酸銀溶液を還元して銀を析出させ, フェーリング液と反応して赤褐色の Cu2O を生じ る。EにはDのような反応性はない。また,化合物Jには鏡像異性体(光学異性体)があるが, Iにはない。 た。次に、Dを本に 問1 化合物 A, B, C の構造式を記せ。 (a) 問2 下線部(a)の官能基をもつ化合物は,一般にどのような反応をするか。 炭素数1の化合物 物について, 例を二つ化学反応式で示せ。 よろ 問3 下線部(b)の反応において, Dはどのような化合物に変化するか。 構造式を記 問4 下線部(c) を参考にして,化合物Jの鏡像異性体(光学異性体)の違いがわかるようにそれ ぞれの構造式を図示せよ。

青くしてある文の文構造と訳し方を教えていただきたいです🙇‍♀️ また、mainstream America の語順に違和感を感じていて、(American mainstream とした方が正しくない?と思ってしまいます、、)それも解説いただきたいです。

Neil Hello. This is 6 Minute English from BBC Learning English. I'm Neil. Georgie And I'm Georgie. Neil If I told you I'd been for a walk to see Big Ben and Buckingham Palace, you'd know straight away I was in London. Georgie But what if my walk went past cafes selling mozzarella and ricotta where I smelled freshly made cannolis and focaccia... Where would I be then? Neil Focaccia and mozzarella... you'd be in Italy, right? Georgie Yes, Italy, or 'Little Italy' to be exact - the neighbourhood in some cities where Italian communities settled and made their home. Neil These Italian arrivals opened shops and cafes selling food to their own communities. Soon dishes like spaghetti and meatballs attracted the attention of local people, and gradually Italian food became famous around the world. In this programme, we'll be taking a walk through two Little Italys, one in Argentina, the other in New York, and, as usual, we'll be learning some useful new vocabulary as well. But before that, I have a question for you, Georgie. According to a recent YouGov poll, which Italian food is most popular with British diners? Is it: a) pizza? b) lasagne? or c) garlic bread? Georgie I think it must be pizza. Neil Okay, Georgie, I'll reveal the answer at the end of the programme. One country Italians moved to was Argentina. In 1898, Giuseppe Banchero arrived in the neighbourhood of La Boca, the Little Italy of Buenos Aires, where many Italian immigrants started restaurants. Here, Hugo Banchero, grandson of Giuseppe, tells his story to Veronica Smink, reporter for BBC World Service programme, The Food Chain: Hugo Banchero Well, my grandfather came from Italy, from Genoa, from Liguria. He was born in the centre of Genoa and arrived here in 1898 at the age of seven and a half, and this pizzeria where we are was founded on March 28, 1972. We have been here for 91 years. Veronica Smink So what culinary traditions did they bring with them? Hugo Banchero Well, our culinary tradition is pizza, and we incorporated the faina from Genoa, which is a pizza with chickpea flour... Georgie In 1898, Giuseppe founded his pizzeria - a restaurant selling pizza. When a business is founded, it's established someone starts it, or sets it up. Neil Giuseppe brought the culinary traditions from his home in Liguria in northern Italy, including regional pizzas like faina and fugazzetta. The adjective culinary describes anything connected with cooking. Georgie But probably the best-known Little Italy in the world is an area of Manhattan's Lower East side in New York. Ninety percent of Italian immigrants who arrived in the US at the turn of the century came through this neighbourhood. Neil De Palos, one of the original shops selling Italian food in Little Italy, has been serving customers for 113 years. Here, Lou De Palo, co-owner and great-grandson of the original owner, Salvino, explains more about his family history to BBC World Service programme, The Food Chain: Lou De Palo 1925... when my grandmother, Concetta, and my grandfather, Luigi, got married, they open their own shop... it's the shop we continue today being the fourth generation working alongside my sister, Maria, my brother, Sal, and our children, the fifth generation. Our business has expanded; expanded to present the full food culture of the 20 regions of Italy. Little Italy is the stepping stone of the Italian immigrant. This is where many of the Italians first came through Ellis Island, and then settled here, and then eventually moved into mainstream America throughout the rest of the country. Georgie Lou De Palo is the fourth generation of his family to run the shop, and his children will be the fifth. Phrases like fourth or fifth generation describe the children of people whose parents immigrated to a particular country.
