Question

What is the molecular formula of a hydrocarbon that has 2 triple bond, 1 double bonds, 1 ring, and 34 carbons?

Answer 1

If the hydrocarbon is completely a ring without any double and triple bonds its molecular formula would be of the form CnH2n

Where, n = number of carbons

So, its molecular formula would be C34H68.

but the question says it has two triple bonds ( 2 pi bond in each triple bond) and 1 double bond ( 1 pi bond in each double bond) which means it has total 5 pi bonds. So, we can say five hydrogens are being substituted by five pi bonds.

Therefore molecular formula would be

=C₃₄H_{(68 - 5)}

= C₃₄H₆₃

Again
