Answer: 2-methyl-2-buthene.. Bcoz it releases H2O (OH- & H+), the OH- need to take one of H+ in the Carbon chain... C-C-C(OH)-C The question is which H will be 'sucked' by OH+?? OH is the border beetwen C-C and C, right?? More C it has, more positive it will be.. H+ is positive, so C-C that more (+) than C, wont bond H better than C (bcoz C is more negative than C-C, so H+ will like C more than C-C).. So, the answer must be C-C=C(CH3)-C and H2O...
