Answer:
The correct answer is -
3. Butyne
4. Pentene
Explanation:
The names of such organic compounds are classified on the number of the carbon atoms and based on a number these prefixes are attached -
Meth - one carbon
Eth - two carbons
Prop - three carbons
But - four carbons
Pent - five carbons, and so on
The bonds can be identified by names of an organic compound by their suffixes -
- ane = single bond
- ene = double bond
-yne = triple bond
Thus, for question 3, carbon numbers are 4 and triple bond so Butyne, and similarly for question 4, 5 carbon atoms and double bond so Pentene.
