Boron forms electron deficient compounds
WebVerified by Toppr. It is because boron has three valence electrons. It shares three electrons and gets six electrons, i. e. its octet is not complete. Therefore, it forms electron … Web5. Boron forms electron deficient compounds. Comment it. Ans: Compounds of boron are referred to as electron deficient compounds because central boron atom has only three shared pairs of electrons i.e. six electrons. Due to the electron deficient nature , boron compounds can readily accept lone pairs of electrons from electron rich species. 6.
