1.	an alkane with molecular weight 86 what will be its physical state and molecular formula? Why do we take 12 n? In answer please explain
Answer» Answer: The molecular formula of the alkane is C n H 2n+2 It's molecular weight is 12n+2n+2=14n+2=86. 14n=84 n=6 Hence, the molecular formula of alkane is C 6 H 14 . Since, it gives only two MONOBROMINATION products, the COMPOUND must be 2,3-dimethylbutane.

Answer»

Answer:

The molecular formula of the alkane is C

2n+2

It's molecular weight is 12n+2n+2=14n+2=86.

14n=84

n=6

Hence, the molecular formula of alkane is C

. Since, it gives only two MONOBROMINATION products, the COMPOUND must be 2,3-dimethylbutane.
