Q.4.Write the molecular formula and Draw the structural formula and the electron dot diagram of benzene.
Q.5. Write the number of single bonds and double bonds present in benzene ring.
Q.6. Write three differences between cyclohexane and Benzene.
Answers
Answer:
6...>>The main difference between cyclohexane and benzene is that cyclohexane contains twelve hydrogen atoms bonded to six carbon atoms, two hydrogen atoms per each carbon atom whereas benzene contains six hydrogen atoms bonded to six carbon atoms, one hydrogen atom per each carbon atom
4..The molecular formula of benzene C6H12O6
6
H
6
5..The usual structural representation for benzene is a six carbon ring (represented by a hexagon) which includes three double bonds. Each of the carbons represented by a corner is also bonded to one other atom. In benzene itself, these atoms are hydrogens.
1..Whenever you see a compound comprised of all single bonds it is said to be a saturated compound. Cycloalkene - Although less common, these cyclic hydrocarbons consists of at least one carbon atom double bonded to one another carbon atom.
