For the following compounds, write structural formulas and IUPAC names for all possible isomers having the number of double or triple bond is indicated : (a)C_4H_8 (one double bond ) (b) C_5H_8 (one triple bond )

For the following compounds, write structural formulas and IUPAC names

1.	For the following compounds, write structural formulas and IUPAC names for all possible isomers having the number of double or triple bond is indicated : (a)C_4H_8 (one double bond ) (b) C_5H_8 (one triple bond )
Answer» SOLUTION :(a)Isomers of `C_4H_8` having ONE double bond are : (i)`underset"But-1-ene"(overset4CH_3overset3CH_2-overset2CH=overset1CH_2)` (iv)`underset"2-Methylprop-1-ene"(CH_3-oversetoverset(CH_3)\|C=CH_2)` (B)(i)`underset"Pent-1-yne"(CH_3CH_2CH_2overset2C-=overset1CH)` , (ii)`underset"Pent-2-yne"(CH_3CH_2-C-=overset2C-overset1CH_3)` , (iii)`underset"3-Methylbut-1-yne"(CH_3overset3- oversetoverset(CH_3)\|(CH)-overset2C-=overset1CH)`
