Match List I (Compound) with List II (Nature) and select the correct answer using the code given below the Lists:
|A. Sodium hydroxide||1. Strong acid|
|B. Calcium oxide||2. Alkali|
|C. Acetic acid||3. Weak acid|
|D. Hydrochloric acid||4. Base|
A B C D
(a) 2 3 4 1
(b) 2 4 3 1
(c) 1 4 3 2
(d) 1 3 4 2
Correct Answer : b ) bExplanation :
Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. Calcium oxide is base and Acetic acid is a weak monoprotic acid. Hydrochloric acid is strong acid.
Hence, option (b) is correct.
