Question

Atactic polymer is that in which?

(a) Alternate chiral centres have the same configuration

(b) Every third chiral centre has the same configuration

(c) Each chiral centre has the same configuration

(d) A complete random distribution of configuration is there

I had been asked this question in an interview.

I want to ask this question from Stereo Structure of Polymers in chapter Polymers of Engineering Chemistry I

Answer 1

The correct answer is (d) A complete random distribution of configuration is there

To explain I would say: Atactic polymer is that in which a complete random distribution of configuration is there. Atactic polypropylene has little order in the polymer backbone and is amorphous.
