1.BF3\mathrm{BF}_3BF3 and NF3\mathrm{NF}_3NF3, both molecules are covalent, but BF3\mathrm{BF}_3BF3 is non-polar and NF3\mathrm{NF}_3NF3 is polar. Its reason isa.In uncombined state boron is metal and nitrogen is gasb.B–F bond has no dipole moment whereas N–F bond has dipole momentc.The size of boron atom is smaller than nitrogend.BF3\mathrm{BF}_3BF3 is planar whereas NF3\mathrm{NF}_3NF3 is pyramidalLogin to continueOnly logged in users canattempt or see the solution.
