    Can you please explain further more for the Q27? Can you also please draw (CH3)3CCH2OH? I thought it is a tertiary alcohol? And why is it resistant to dehydration but not the second one? Sorry! But Thank you so so much! Next time I will include answers in it :)

    8) I hope that your are familiar with Equations for linear motion. ( Do not confuse with Newton's laws of motion). They are: 1) v = u + a*t 2) s = u*t + 1/2 *a*t^2 3) 2*a*s = v^2 - u^2 Here v stands for final velocity, u stands for initial velocity, s means displacement, t stands for time and a...
