`H_(2)C=CH-CH-=CH` on reaction with one mole DBr gives:

When CH_2=CH-O-CH_2-CH_3 reacts with one mole of Hl, one of the products formed is

When CH_2 = CH -O - CH_2 - CH_3 reacts with one mole of HI , one of the products formed is

A : When C_(2) H_(5) - O- CH_(3) is reacted with one mole of Hl then C_(2)H_(5)OH & CH_(3) I is formed . R : It is S_(N)1 reaction

An organic compound on reaction with O_(3) followed by Zn and H_(2)O gives CH_(3)-overset(O)overset(||)(C )-CH_(2)-CH_(2)-overset(O)overset(||)(C )-CH_(3) . The structures are:
