Assertion: Addition of Br(2) to 1-butane...

Assertion: Addition of `Br_(2)` to `1`-butane gives two optical isomers.
Reason: The product contains one asymmetric carbon atoms.

A

Statement `I` is true, Statement `II` is true, Statement `II` is the correct explanation of Statement `I`.

B

Statement`I` is true, Statement`II` is true, Statement `II` is not the correct explanation of Statement `I`.

C

Statement `I` is true, Statement `II` is false.

D

Statement `I` is false, Statement `II` is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`CH_(3)CH_(2)CH=CH_(2)+Br_(2)rarrCH_(3)CH_(2)-overset(Br)overset(|)underset(**)(C)H-underset(Br)underset(|)(C)H_(2)`
Number of optical isomers `=2^(n)=2^(1)=2.`
Hence, both statement `(I)`and statement `(II)` are correct and statement `(II)` is the correct explanation of statement `(I)`.
