Assertion:-Acetylene give.sglyoxal on reductive ozonolysis while benzene does not give glyoxal.

Reason:- Benzene does not show reductive ozonolysis reaction.

View answer and explanation

Correct option: D

If both Assertion & Reason are false

In benzene, there is a delocalisation of π-electrons. Hence, each π-electron is attached by….carbon nuclei. Which statement is false? Assertion (A) In comparison to ethyl chloride, it is not easy to carry outnucleophilic substitution on vinyl chloride.

Reason (R) Vinyl group is an electron donating. If 2-oxopropanal and methanal are obtained by the reductive ozonolysis of compound (A), then the number of
