- Electrophilic aromatic substitution usually occurs at the 1-position of naphthalene, also called the a position. Predict the major products of the reactions of naphthalene with CH3CH2COCl, AlCl313-B Do aromatic rings have double bonds? Are they unsaturated? Explain.1. Draw an aromatic ring, which contains only hydrogens and 5 carbons; add charges and lonepairs if needed 2. Draw a non-aromatic ring which contains only hydrogen and 5 carbons and have conjugateddouble bonds; add charges and lone pairs if needed.

- Electrophilic aromatic substitution usually occurs at the 1-position of naphthalene, also called the a position. Predict the major products of the reactions of naphthalene with cyclohexanol and BF3OChem help with IUPAC names involving Ph and Bn The phenyl group (Ph-R, C6H5-R) can be formed by removing a hydrogen from benzene and attaching a substituent to where the hydrogen was removed. The benzyl group (abbv. Bn), similar to the phenyl group, is formed by manipulating the benzene ring. In the case of the benzyl group, it is formed by taking the phenyl group and adding a CH2 group to where the hydrogen was removed. Its molecular fragment can be written as C6H5CH2-R, PhCH2-R, or Bn-R. Please provide the IUPAC name for the following: (Ph)2CHC(CH3)2CC(CH2)3CH(Bn)CHOElectrophilic aromatic substitution usually occurs at the 1-position of naphthalene, also called the a position.
