Question

Which of the following molecular formulas corresponds to a monocyclic saturated compound?

A) C6H6

B) C3H7Br

C) C3H7N

D) C3H8O

Answer 1

The correct option is e.

None of the provided molecular formulas (A, B, C, D) corresponds to a monocyclic saturated compound; all of them are either unsaturated or lack a cyclic structure.

To determine which of the given molecular formulas corresponds to a monocyclic saturated compound, let's analyze each option step by step:

A) C6H6 - This formula corresponds to benzene, which is a monocyclic aromatic compound. It is not saturated because it contains alternating double bonds.

B) C3H7Br - This formula corresponds to 1-bromopropane, a linear saturated compound. It is not monocyclic because it doesn't have a cyclic structure.

C) C3H7N - This formula corresponds to propylamine, a linear saturated compound. It is not monocyclic because it doesn't have a cyclic structure.

D) C3H8O - This formula corresponds to propanol, a linear saturated compound. It is not monocyclic because it doesn't have a cyclic structure.

None of the given options corresponds to a monocyclic saturated compound, so the correct answer is none of the above (E) because there is no option that matches the criteria.

The complete question is here:

E) none of the above

Answer 2

The molecular formula corresponding to a monocyclic saturated compound is C₆H₆. Thus the correct option is A

Step-by-step explanation:

Among the given options, the molecular formula C₆H₆ represents benzene, a monocyclic saturated compound.

Benzene has a ring structure consisting of six carbon atoms, each bonded to one hydrogen atom. It is a saturated compound as it contains only single bonds between carbon atoms within the ring.

The other options (B, C, D) contain different elements or configurations that do not match the criteria of a monocyclic saturated compound. For instance, C₃H₇Br represents a brominated compound, C₃H₇N represents amines, and C₃H₈O corresponds to an alcohol, none of which are monocyclic and saturated like benzene.

Therefore, the correct choice among the options provided is C₆H₆, which corresponds to a monocyclic saturated compound, specifically benzene, meeting the criteria of the question.

Therefore, the correct option is A.
