キラルについて。

英語の文章なんですけど、 Which statement is true about a chiral compound and its enantiomer? (1) They can always be interconverted by rotation about single bonds. (2) they rotate plane-polarized light the same number of degrees and in the same direction. (3) They have the same melting point and the same boilder point. (4) They are superimposable upon their mirror images. 一応やくしてみたんですが、(1)から(4)でどれがキラルの合成物に対して正しいですか? (1)単結合の回転は、常に交換できる。 (2)??? (3)同じ沸点、融点をもっている。 (4)???

回答No.2

inorganicchemist さんの回答に補足です。 (3)それらは同じ融点と同じ沸点を持っている。:T (4)それらはそれらの鏡像体と重ね合わせることができる。:D  キラル化合物 A はその鏡像体 A' と重ね合わす事は出来ませんし,エナンチオマ- A' もそのエナンチオマ- A と重ね合わす事は出来ません。したがって,これは間違いです。 ところで,これは何でしょうか。似たような英語の質問が先程もありましたが。

回答No.1

(1) それらは単結合まわりの回転によって常に変換される。:D (2) それらは面偏光を同じ方向に同じ強度だけ回転させる。:D (3) boilderがわかりませんので保留。 (4) それらはそれらの鏡像体と重ね合わせることができる。:T

  • 角度などの表現

    以下の文章ですが、形にして頭で想像できない箇所があります。 一文ずつ画像で想像するならば、どうなるでしょうか。 (1)“Lateral files” are a kind of file drawer – file system where the files are facing either left or right. (2)Normally when you have a file cabinet, you pull out the drawer and the files are all facing you. (3)In other words, they are in a direction so you can read them easily. (4)To have a “lateral file” means that the files are basically at 90 degrees from where you are so that they don’t face the same direction as the drawer pulling out, they face in a perpendicular direction. 以上です。 (1)の文ですが、 the files are facing either left or right は、どういう状態でしょうか。 (2)の文もface という動詞が出てきます。 the files are all facing you (3)の文章は(2)を言い換えていますが、 they are in a direction  はどういう状態でしょうか。簡単に読めるように in a direction になっているようですが・・・ (4)は “lateral file”を説明していますが、  at 90 degrees from where you are というのがどうも想像できません。   そして、なんのために90度の角度かというと、they don’t face the same directionのためと書いて  ありますが、又face が出てきて想像できませんでした。 “Lateral files”と、ノーマルのfile cabinetを比較している文章だと思いますが、 絵に浮かべなくています。 よろしくお願いいたします。

    Several international reports warn that global warming is nearing the point of no return and urge the world to seriously address the problem. They all point out that in 20 years the Earth could be an average 2 degrees warmer than it was in 1750, or before the industrial revolution, and that its consequences could include rising sea levels, major droughts and increased disease.The global temperature has already risen by 0.8 degrees since 1750, so the world has little more than a single degree of temperature latitude before the crucial point is reached.

If a face and a phone appeared at the same place and time, the system grew more confident they belonged to the same person. Over four days in April, the boxes identified more than 67,000 phones. The cameras captured more than 23,000 images, from which about 8,700 unique faces were derived. Combining the disparate data sets, the system matched about 3,000 phones with faces, with varying degrees of confidence. 元ネタはNYT A Surveillance Net Blankets China’s Cities, Giving Police Vast Powers

  • 隣接角について

    こんにちは、 英文交じりの質問で申し訳ないのですが、宜しくお願い致します。 隣接角(Adjacent Angles)の定義は知ってます。 そして、隣り合ってる角の合計は180 ° まで、と解釈してます。 (Adjacent Angles Two angles are Adjacent if they have a common side and a common vertex (corner point) Adjacent angles add up to 180 degrees.) が、図のaからdまでの角度の合計がa + b + c + d = 360 ° の証明に adj ∠’s at a point sum to 360 °となってるのをみました。 隣接角は180度までなのに理解できません。それとも”adj ∠’s at a point sum to 360 °”は間違っているのでしょうか? どなたか説明して頂けますか?
