Question

Assertion `(A)` : All the `C` atoms of but-2-ene lie in one plane
Reason `(R )`: Double-bond `C` atoms are `sp^(2)`-hypbridised.
A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation for `(A)`.
B. If both `(A)` and `(R )` are correct and `(R )` is not the correct explanation.
C. If `(A)` is correct and `(R )` is incorrect.
D. If both `(A)` and `(R )` are incorrect.

Answer 1

Correct Answer - A
Both `(A)` and `(R )` are correct and `(R )` is the correct explanation for `(A)`. As `sp^(2)`-hybridised `C` atoms are planar, they lie in one plane
