Question

What is the molecular formula of a hydrocarbon that has 1 triple bond, 2 double bonds, 1 ring, and 32 carbons?

Short answer

The molecular formula is C₃₂H₆₆.

Step-by-step solution

Step 1:Definition of molecular formula-

The number of atoms of each element in one molecule of a chemical is expressed by the molecular formula.

The molecular formula is a formula that shows the exact number of atoms in a molecule.

Definition of degree of unsaturation-

The degree of unsaturation (sometimes called the index of hydrogen deficiency (IHD), double bond equivalents, or unsaturation indexis a computation that determines the total number of rings and bonds in a compound.

The molecular formula of a hydrocarbon that has 1 triple bond, 2 double bonds, 1 ring, and 32 carbons. 

The molecular formula of the hydrocarbon isC₃₂H₆₆.

With the one triple bond, two double bond and one ring, the degree of unsaturation is 5.

Therefore, the compound is missing 10 hydrogens from C_nH_2n+2 =C₃₂H₆₆.
