化学頻出スタンダード問題230選 問2マーカー部の問題がよくわかりません 水素結合がある方が融点や沸点が高くなることは知っています。しかし、どのように水素結合が発生しているかどうかを判断したのでしょうか

第15問 結合の極性と分子間の引力 2個の原子からなる分子では,原子間の結合は主に (ア) 結合である。 しかし,各原 子の(イ)が異なる場合は, 原子間の(ウ) がどちらかの原子の方にかたよることに より,一方の原子は正の電荷を帯び, 他方の原子は負の電荷を帯びる。 このような電荷の かたよりを結合の極性という。一般に, (イ)の値が等しい2原子間の結合には極性 がない。 分子全体の極性は,分子を構成する各結合の極性と分子の立体構造の両方がわかれば, ほぼ正確に決めることができる。 例えば分子が直線形の二酸化炭素および(エ)形の四 塩化炭素は (オ) 分子であり, 直線形の塩化水素や (カ)形の水および (キ) 形の アンモニアは(ク) 分子である。 水素原子が (イ)の大きい窒素(ケ), フッ素などの原子と結合すると、 結合の極 性がかなり大きくなり分子間に強い静電気的引力が働くようになる。 このような分子間で 働く結合をコ)という。 問1 (ア)~(コ)にあてはまる適切な語句を書け。 問2 分子式が同じエタノール(C2H5OH) とジメチルエーテル (CHOCH)では,前者の 沸点が後者のそれに比べはるかに高い。 この理由を25字以内で書け。 (昭和薬科大〈改〉)

SIMなし合 22:01 Cop 【1】次の英文を読んで, 設問 1~12に答えなさい。 なお, *印の語(句)には文末に注 がついています。 Modern examinations of working conditions in British and U.S. industry in the nineteenth and early twentieth centuries concentrate mainly on the experiences, Complaints, and overall difficulties of working-class laborers. The first complaint that a majority of industrial workers had was that their workdays* were too long. The average (ア) of hours in a shift varied from industry to industry, from place to place, and from era to era. Workers in British and American textile mills* in the early to middle 1800s generally worked twelve to fifteen hours, six days a week, ( イ) only Sundays off. Their average workweek* was seventy-eight hours. In contrast were the hours of workers who labored in American steel mills in the late 1800s. The length of their shifts was determined by the fact that the blast furnaces* they tended almost always operated twenty-four hours a day. Thus, (oit became customary* for steel mills to have two twelve-hour shifts. However, many of the steel workers labored seven days a week. (a)That gave them a workweek of sighty-four hours. Moreover, sometimes they had to work extra hours on top of this demanding schedule. (オ )the minor differences in the length of workweeks from one industry to another, the average worker put in twelve-to fourteen-hour days at least six days a week, This harsh schedule remained more ( カ) less standard well into the twentieth century. It was not until 1920 that a fifty-hour workweek was introduced in the United States. Anda forty-hour week did not become the rule in most industries until 1938. Low wages was another common complaint of industrial workers. In 1851, the average wage earned by American industrial workers in general was seven to ten dollars per week. That same year New York's Daily Tribune* reported that a worker's family of five required just over ten dollars a week just for basics such as rent, food, and fuel. Most ordinary workers could not afford many simple comforts that middle-class workers enjoyed. (o This miserable situation lasted in America for decades and improved only slowly. As late as 1912, a study found that only 15
