Answer 1

Q.1 Draw the following compounds.

1. Ethylcyclobutene- Here the root is cyclobutene. Now butene means a compound having four carbon atom with a double bond and the prefix cyclo means the four carbon atoms are arranged in a cyclic manner. And an ethyl group is attached to the cyclobutane ring. Here since the position of ethyl group is not indicated we assume it to be at the first position starting from the double bond. The structure is aa follows:

2. Meta-isopropyltoluene. Here the root compound is toluene. Toluene is a compound in which hydrogen from the benzen ring is substituted by methy group. The carbon to which the methyl group is attached is the ipso-carbon. The carbon adjacent to the ipso carbon is the ortho carbon. Next to ortho carbon is the meta position and right opposite to ipse carbon is the para position. Now the isopropyl group is a compound in which there are three carbon atoms and the attachment is through the second carbon. Thus the structure is:

eh 9 CH 3

3. Acetone: The suffix -one indicates that it is a ketone. Ketones have a carbonyl group and ethyl groups at both the ends. Acetone is also known as propanone. Thus the structure is

CH-C-CH

4. An alkyne with formula C₄H₆: Alkynes have a general molecular formula of C_nH_2n-2 that has a triple bond. The structure is.

CH C=C-CH
