Answer 1

Here cl- is bonded 2) Geminal dihalide i Two halogen atoms ich is bonded to that carbon who is further ided to 3 - Carbon. Hence it is testairy (3) chloride Two halogen atoms bonded to the same carbon atom 3,3-dichloro pentaine catom to two 13) Secondary Alkylt involved in C-x bon Carbon also. condary Alkyl halide are those in which in c-x bonding should bonded To isopropyl chloride 14) HC.
