A) \[sp\] hybridized
B) \[s{{p}^{2}}\]hybridized
C) \[sp\] and \[s{{p}^{2}}\] hybridized
D) \[sp,\] \[s{{p}^{2}}\]and \[s{{p}^{3}}\]hybridized
Correct Answer: C
Solution :
On passing alkynes (acetylene) through ammoniacal cuprous chloride solution, a red precipitate of cuprous acetylide is obtained. \[CH\equiv CH+C{{u}_{2}}Cl+2N{{H}_{4}}OH\xrightarrow{{}}\]\[\underset{\begin{smallmatrix} cuprous\,acetylide \\ (red\,\,ppt) \end{smallmatrix}}{\mathop{CuC\equiv CCu}}\,+2N{{H}_{4}}Cl+2{{H}_{2}}O\]while this reaction is not given by alkenes (ethylene).
