Dear student kindly paste the questions one by one.
Hybridisation in organic compounds can be decided by looking the type of bond between the atoms. For ex. in case there is single bond between C,C the hybridisation will be sp3, for C,C double bond it will be sp2,and for C,C triple bond the hybridisation will be sp.
Lone pairs are those electrons which do not participate in bonding,such electrons causes distortion of geometry of the molecule because of repulsion between either with other lone pairs or with bond pairs.Such electrons do not participate in hybridisation.Like in case of ammonia molecule(NH3) presence of 1 lone pair decreases its bond angle from normal tetrahedral angle 109 degree to 107 degree making its geometry pyramidal and in H2O molecule bond angle decreases to 104.5degree because of 2 lone pairs repulsion the geometry becomes bent,or angular.
