Not this
The molecule contains a diol group.
Use this
The molecule contains two hydroxyl groups.
在化学英语中,'diol'指含有两个羟基的化合物整体,而非官能团。官能团应称为'hydroxyl group'。此处错误地将'diol'当作官能团使用,源于中文'二醇基'的直译。
Not this
I need to diol my friend.
Use this
I need to dial my friend.
'diol'是名词,意为'二醇',不能用作动词。而'dial'是动词,表示'拨打电话'。此错误属于词性混淆,可能因拼写相似且中文'拨号'发音与'dial'相近所致。
