The names of these constitutional isomers are cyclopentane, methylcyclobutane, ethylcyclopropane, and 1,1-dimethylcyclopropane.
Constitutional isomers have the same molecular formula. This means that they have the same number of carbon and hydrogen atoms, with a general formula of:
When we consider the possible structures, the first option is cyclopentane, the simplest five-membered ring. When we reduce the ring to four carbons, we have the methylcyclobutane and when we reduce it to three carbons, we can arrange the other two carbons in an ethyl group or we can put two methyl groups on a single carbon atom to get the final two constitutional isomers.

Answer : The velocity of the spaceship is,
Solution :
As we are given that,
The speed of a spaceship = 7.58 wraps
So,
The speed of light =
Now put the value of speed of light in above expression, we get
So,
The velocity of the spaceship =
Now we have to convert the velocity of the spaceship m/s to cm/min.
Conversion :
(1 m = 100 cm)
(1 min = 60 sec)
The velocity of the spaceship =
Therefore, the velocity of the spaceship is,
