**Question 2:***What is the IUPAC name of the following compound?*[Diagram of a cyclohexane ring with two substituents: one methyl group and one ethyl group]Options:- A) 1-ethyl-2-methylcyclohexane- B) 2-ethyl-1-methylcyclohexane- C) 1-ethyl-2-methylhexane- D) cyclononane*Explanation of Diagram:*The diagram displays a six-membered carbon ring, indicating a cyclohexane structure. It has two substituents: - A methyl group (CH₃) is attached to one of the carbon atoms, shown as a small line branching from the ring.- An ethyl group (C₂H₅) is attached to another carbon atom, depicted as a longer line branching outward.The task is to determine the correct IUPAC name for this structure by considering the position and size of the substituents on the cyclohexane ring.

The given compound is a hydrocarbon, cycloalkane. The IUPAC name of a cycloalkane can be written on the basis of the number of carbon atoms in the ring, and substituents.The root name of the organic molecule is written on the basis of the number of carbon atoms in the main carbon atoms ring, the prefix is used on the basis of the substituents. The numbering of the carbon ring is as follows: The numbering of the carbon chain is done from that end which gives a minimum number to the substituent on the basis of alphabetical order of the name of the substituent.The given compound contains a six-carbon atoms ring; hence the name of the compound is derived from cyclohexane. The ring contains an ethyl substituent at C-1 and a methyl substituent at C-2. The name of the substituents is written in alphabetical order. Hence the name of the compound is = 1-ethyl-2-methylcyclohexane. The correct option is as follows: A) 1-ethyl-2-methylcyclohexane
