80% carbons is present in an alkane by weight. The possible conclusion

1.	80% carbons is present in an alkane by weight. The possible conclusions are
Answer» The emperical formula of the COMPOUND is `CH_(3)` The minimum number of carbons in the molcule is 2 The compound has gram atoms of C & H in 4:1 ratio This composition suits to all alkanes Solution :`{:(,"C",,"H"),(,80G,,20g),("moles =",(80)/(12),:,(20)/(1)),(,1,:,3):}` `(n)/(2n+2)=(1)/(3)impliesn=2`
