Answer :
The given statement about the number of bonds in the DEET molecule is false. DEET has 31 sigma bonds and 4 pi bonds in it.
DEET (N, N-Diethyl-m-toluamide) is an insect repellent used to protect against insect-borne diseases such as malaria, Lyme disease, and West Nile virus. DEET consists of an aromatic ring attached to a methyl group and an amine group.
The aromatic ring contains two double bonds (pi bonds) and two single bonds (sigma bonds), giving it a total of four pi bonds and six sigma bonds. The methyl group and amine group each contain three sigma bonds, giving DEET a total of twelve sigma bonds.
Finally, the interaction between the aromatic ring and the methyl and amine groups creates an additional fifteen sigma bonds, giving DEET a total of twenty-seven sigma bonds. In addition, DEET contains four pi bonds, two from the aromatic ring and two from the interactions between the aromatic ring and the methyl and amine groups. This gives DEET a total of thirty-one sigma bonds and four pi bonds.
