Q. In vinyl acetylene $C H \equiv C - C H = C H_{2}$ , type of overlapping in $(C_{2} σ C_{3})$ bond is

$s p^{2} - s p$

$s p - s p^{2}$

$s p^{3} - s p^{3}$

$s p^{3} - s p^{2}$

When $(C = C)$ bond and $(C \equiv C)$ bond are present, numbering is done from $(C = C)$ side. Thus, $(C_{2} \underline{σ} C_{3})$ is formed by $(s p^{2} - s p)$ overlapping

Q. In vinyl acetylene CH≡C−CH=CH2​, type of overlapping in (C2​σC3​) bond is
