CBSE Class 11-science Answered

sir/ madam, 1. is it true that if no of bonds in an atom increases then the atom acquires a positive charge on it and when it loses one bond it acquires a negative charge on it? why does it happen so?   2. I heard that alkenes and alkynes are electron-rich species. is it true? why plz explain

1. Already answered in previous query.
 
 
2. The pi bond is a weaker bond due to poor sideways overlapping between the two 2p orbitals. Thus,the presence of the pi bond makes alkenes and alkynes behave as sources of loosely held mobile electrons. Alkenes and Alkynes are also having shorter bond length. Due to presence of  loosely bound pi electrons, alkenes and alkynes are unstable and electron rich compounds as comapared to alkane.
