この問題の(2)-(a).(c)がわかりません💦

第6問 (必答問題) 下の図は物質の三態を模式的に表したものであり、一つ一つのが分子1粒 を表している。 以下の図から、状態が固体から液体、液体から気体へと変化する と粒子間の距離が広がっていくことがわかる。 また、 全ての粒子には分子間力が 働いていることがわかっている。 温度を上げていくと粒子の熱運動が激しくな り、粒子間の分子間力を引き払う粒子が多くなり、結果として状態が固体から液 体、液体から気体へと変化することがわかる。 すなわち、 物質の三態は分子間力 と熱運動の大小関係で決まるといえる。そのため、分子間力が強い分子ほどその 力を振り払うために必要な力も大きくなるため、沸点や融点は ア なることがわかる。 固体 液体 -9- 気体 一口iォンの含まれる③のCuSO4のよっ +NaClと④CmH22O1のどちらか。 Art C₁2H12011 (1) 文中のアに入る語句として適当なものを選べ。 ① 高く ②低く (2) 物質の沸点と分子間力の大きさの関係に興味をもった生徒A はさまざまな 文献で調べたところ以下のことがわかった。 (i) 構造のよく似た分子では、分子間力は分子の重さが重いほど強く働く。 (i) 重さが同程度の場合、 分子間力は無極性分子よりも極性分子の方が強く働 く。 () 電気陰性度の大きな原子と水素原子が結合した分子は 「水素結合」という 分子間力を有しており、 その強さは一般的な分子間力よりも圧倒的に強い。 ただし、HC1 は水素結合をもたないことがわかっている 以上を踏まえて、(a)~ (c) の物質の組み合わせについて、 それぞれ沸点が最も 高いと考えられる物質はどれか、一つ選びマークせよ。 ただし、必要であれば分 子の重さは資料1を参考にすること。 (a) ① HF② HC ③ HBr 46 (b) ①Fz ② Clz ③ Brz \47 (48 (c) ① F2 ②HCl ③ Oz 20 45 3 H He Li Be BCN OF No Nang AlsiPs clar KCa -10- F2 Cl2 Br₂ HCl O2 重さ 38 72 160 37 32 資料1 重さは水素原子の重さを1とした時 の相対的な重さを記してある。 193680
