❌ 错误:This is a carboxylic.
✓ 正确:This is a carboxylic acid.

carboxylic 是形容词,不能单独用作名词;应加上 acid 或其他名词,如 carboxylic group,以构成完整术语。

❌ 错误:The carboxylic acid is very strong.
✓ 正确:Carboxylic acids are generally weak acids.

羧酸通常是弱酸,而非强酸;学习者可能误用强度描述,需注意化学性质的正确表达。

近义词辨析

acidic

acidic 泛指酸性或含酸的,而 carboxylic 特指含有羧基(-COOH)的,更专业和具体;例如,所有羧酸都是酸性的,但并非所有酸性物质都含羧基。

Lemon juice is acidic due to citric acid, which is a carboxylic acid.

organic acid

organic acid 指有机酸,是一个更广泛的类别,包括羧酸和其他类型;carboxylic acid 是 organic acid 的一种,特指含有羧基的有机酸。

Acetic acid is a carboxylic acid and also an organic acid, but not all organic acids are carboxylic.
