In the following reaction CH_3-CH_2-CH_2-CH_3 underset"475 K"overset(H_2SO_4)to

Answer»

`CH_3CH=CHCH_3` predominates
`CH_2=CHCH_2CH_3` predominates
Both are FORMED in equal amounts
The amount of production depends on the nature of catalyst

Solution :`CH_3-CH_2-CH_2-CH_3underset"475 K"overset(H_2SO_4)to underset"More symmetrical (MAJOR PRODUCT )"(CH_3-CH=CH-CH_3)`
`CH_3-CH_2-CH_2-CH_3underset"475 K"overset(H_2SO_4)to underset"Less symmetrical for UNSYMMETRICAL (MINOR product)"(CH_2=CH-CH_2-CH_3)`
It is based onSaytzeff's rule . According to this more symmetrical or more alkylated alkene predominates.
