Why alcohols do not undergo base induced dehydration in the same way that alkyl halides are dehydrohalogenated ?

In the dehydration reaction of alcohols the leaving group is -OH^- which is a very strong base. Thus reaction cannot proceed in the presence of other base.

Why do the C-C bonds rather than the C-H bonds break during pyrolysis of alkanes ?

During pyrolysis C-C bond break first because bond energy of C-C bond is lower than the bond energy of C-H bond. The C-C bond energy is 83.0 kcals while C-H bond energy is 98.8 kcals. Thus, C-C bond break more easily than C-H bonds.

Is Benzcne same as 1,3,5-Cyclohexatriene ?

In 1,3,5-Cyclohexatriene, there are three >C=C< (double bond ) having bond length 134 pm and three C-C (single bond) having bond length 154 pm, whereas in benzene all the six C-C bonds have same bond length 139 pm. Due to that fact 1,3,5-Cyclohexatriene give addition reaction while benzene does not. Thus benzene is not same as  1, 3,5-cyclohexatriene.
