Naming organic compounds: multiple choice

3) C: Structure should have 6 carbon with double beginning on the 2nd carbon atom.

4) D: structure should have 5 carbon with triple bond beginning on the first carbon atom.

5) A: 4

Explanation:

3) The molecular formula for hexene is C6H12. This means it has 6 carbon atoms. However, the suffix "ene", means that it contains an alkene and thus it has 2 double bonds connecting 2 carbon atoms.

Looking at the options, the correct one is Option C.

4) The molecular formula for 1-pentyne is given by; C5H8.

This means there are 5 carbon atoms. However, the suffix "yne" means there is a presence of ethyne and thus it has triple bond.

Looking at the options, the only correct one is Option D

5) Since the number of carbon atoms are 3 and it has triple bond, then it means this is likely propyne

Now, the formula is C3H4 which is;

chemical formula CH3C≡CH

Thus, the number of hydrogen atoms with at least 1 carbon-carbon triple bond is 4.
