Assertion : In `CH_(3)NCO`, the angles `C - N - C` and `N - C - O` are not identical
Reason :N- atom has a pair of electrons which is involved to `p pi - d pi ` delocalisation whereas `C-`atom does not have lone pair of electrons.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer

A

Explanation

`BF_(3)` is an electron deficient molecule and `Me_(3)N` is an electron rich molecule. The electron pair on nitrogen atom in `Ph_(3)N` is delocalized in benzene rings and not available to boron in `BF_(3)`
