In the first step of a Wittig reaction, what will happen if you use chlorobenzene instead of benzyl chloride? Why a) the yield will increase, because chlorobenzene is a better nucleophile b) yield will be slightly decreased, because chlorobenzene is a poorer nucleophile c) no product will form,  chlorobenzene cannot be converted to a phosphonium chloride salt d) no alkene product will form the phosphonium salt from chlorobenzene reacts with chloro benzene to form triphenyl magnesium chloride.   e) no noticable change will be detected, benzyl chloride

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.
