Given below are two statements, one is labelled as Assertion and the other is labelled as Reasom .
Assertion : A solution of the product obtained by heating a mole of glycine with a mole of chlorine in presence of red phosphorous generates chiral carbon atom.
Reason : A molecule with chiral carbons is always optically active.
In the light of above statements, chose the correct answer from the options given below:
Assertion : A solution of the product obtained by heating a mole of glycine with a mole of chlorine in presence of red phosphorous generates chiral carbon atom.
Reason : A molecule with chiral carbons is always optically active.
In the light of above statements, chose the correct answer from the options given below:
Options
- A
is true but is false
- BBoth and are true but is the correct explaination of
- C is false but is true
- DBoth and are true but is NOT the correct explaination of
Correct answer
A.
is true but is false
Step-by-step solution
When glycine is treated with chlorine in presence of red phosphorus, reaction takes place i.e., substitution of chlorine takes place at alpha carbon.
A molecule with two chiral carbons is not always optically active. Suppose the following compound is having two chiral carbons but optically inactive due to internal compensation of optical rotation.
