Explain why phosphorus can form five covalent bonds, whereas nitrogen can only form three covalent bonds.
Due to hybridization. Phosphorus only 'needs' three more electrons to get a full valence shell of eight, but you'll notice that it actually has five valence electrons, so in theory...

I have to do a reaction with an alkene using CBr4 and RO-OR. Would the peroxide cleave first and then attach the CBr4. If that happens how would the Br attach to the alkene
Addition reactions involving alkenes and alkynes include hydrogenation, halogenation, and hydrohalogenation. Alkenes and alkynes are useful reagents in polymer synthesis—an important industrial application.

why do all polar bonds molecules have polar bonds and all non-polar molecules have non-polar bonds?
Nonpolar bonds form between two nonmetals with the same electronegativity value. Nonpolar molecules may contain any type of chemical bonds, but the partial charges cancel each other out.Polar bonds form...
