    ac actually 35Cl is in 75% occuring in nature and 37Cl is 25% thats y ratio is 3:1

    if 2 Cl are included in mixture say Ch2Cl2 u'll get peaks M (M+2)x2 and M+4 heights ratio 9:6:1 for br2 included u get 1:2:1 ratio stay tune for y part

    a key point for mass spectrometry if M and M+2 peaks are in ratio of 3:1 means chlorine is present if M and M+2 peaks heights are in ratio of 1:1 than Bromine is in mixture (only one bromine)

    nopes the Pi bond formed due to the Carbon p-orbitals overlaps (in double bond) the effective overlap is when the P-Orbitals aligned themselves parallel to each other restricting them to rotate making them rigid in shape

    look for chlorine u have to remember that Cl35 is in thrice time than cl37 similarly for Br 1:1 ka ratio

    for first part no idea maybe Oliveme can help! for the other Question look Reduction is gain of Hydrogen so u r just adding hydrogen with a presence of Nickel think Nickel as a catalyst(it is possibly increasing the surface Area for effective collisions)

    hmm, when some guys are attatched on 1st position like methyl -Oh they activate the 2nd position 4th position where they tend to push the incoming groups to those bootCamps ;)

    yup as H is removed and Carbon is attatched to it instead!
