Question

.An Alkane has molecular weight 86. Write its molecular formula. What will be its physical state?​

Answer 1

Answer:

let the formula of the alkane be CnH2n+2

Therefore we have

12n + 1(2n+2) = 86

12n +2n+2=86let the formula of the alkane be CnH2n+2

Therefore we have

12n + 1(2n+2) = 86

12n +2n+2=86

14n = 84

n=6

i.e the formula of the given alkane is C6H14 !
