which has more dipole moment ?? A) difluoro methane B)di chloromethane
ans; B !! fluorine is more electronegative than chlorine so there is more partial charge in CH2F2 but dipole moment is the product of charge n bond length; here bond length is the dominating factor C-Cl has more bond length than C-F
integral of even function is a) odd always b)even always c) none
ans: c that depends on the integration constant !! if constant is 0 then it's odd else it is neither odd nor even
we have a beaker of water and an ice cube floating on it with a stone over the ice cube what happens when the ice melts?? will the water level increase or decrease??
decreases!! (think twice before you answer; its opposite to your intuition may be)
