A) I think that you are asking about:
..........H....H..........H
..........l......l...........l
... H - C = C - C = C - H
.....................l
....................H
This compound is : but-1,3-diene ( previous 1,3 butadiene) Note the = ( double bonds) on C1 and C3
B) This is the molecule:( I think)
.................H
..................l
H - C ≡ C - C - H
.................l
................H
The name of this is 1-propyne.
Note - you have submitted a = butane and b = propane. These names refer to saturated hydrocarbons ( With all single bonds). In A you have 2 double bonds which means diene,- 4 carbons butadiene , on C1 and C3 but -1,3- diene
and in B you have a triple bond which means a compound named -yne. 3 carbons = prop , with double bond on C1, it is 1- propyne.

I don't understand either...those structures are really messed up! lol
