Identify the longest carbon chain that contains max. no. of functional groups;
identify the naming order (i.e. which end is the no. 1 carbon);
identify the substituents accordingly.

1.
Main chain has ten carbon atoms, so has the name Decane;
has alkene and alkyne in chain, so has the name dec-?-en-?-yne;
alkene has higher priority than alkyne, so has the name dec-2-en-9-yne;
there s a propyl substituent on 5th carbon (counting from alkene-side), so has the full name:
5-propyldec-2-en-9-yne

2.
8 carbons in main chain, hence the name Octane;
there re alkyne and alkanol, thus oct-?-yn-?-ol;
alkanol takes higher priority in arranging (hence with smaller number for its position, thus oct-7-yn-3-ol;
bromine on on 6th carbon, thus 6-bromooct-7-yn-3-ol.
