Question

Which of the following statements are true?

(a) Ethylene is highly soluble in water

(b) Glycol is used in paint emulsions

(c) Aromatics are not produced during steam cracking of hydrocarbons

(d) Acetylene is more acidic than ethylene

The question was posed to me during an online interview.

I need to ask this question from Synthetic Organic Chemical Industries in chapter Synthetic Organic Chemical Industries of Chemical Technology

Answer 1

Right option is (d) Acetylene is more acidic than ethylene

Explanation: Ethylene is slightly soluble in water. Glycol is used as antifreeze but not in paint emulsions. Some of the aromatics are produced as by-products in the steam cracking of hydrocarbons. Acetylene is more acidic than ethylene due to strong overlapping between s and p orbital’s.
