Assertion : Bond order of F_(2) is one . Reaso : ABMO electrons are 2

1.	Assertion : Bond order of F_(2) is one . Reaso : ABMO electrons are 2 unit less than BMO.
Answer» ASSERTION (A) and Reason (R) both are correct and (R) gives correct explanation. Assertion (A) and Reason (R) correct, but Reason is not proper reason. Assertion is correct, but Reason is wrong. Assertion and Reason both incorrect. Solution :Assertion (A) and Reason (R) both are correct and (R) gives correct explanation. `F_(2) (9 + 9 = 18)` `(sigma_(1s))^(2) lt (sigma_(1s)^())^(2) lt (sigma_(2s))^(2) lt (sigma_(2s)^())^(2) lt (sigma_(2pz)^())^(2) lt (pi_(2PX))^(2)= (pi_(2py))^(2) lt (pi_(2p_(x))^())^(2) (pi_(2p_(y)))^(2)` `{:("Electron of BMO =10"),("Electron of ABMO" = 8):}} ` so , BO = `(1)/(2) (N_(b) - N_(a) ) = (1)/(2) (10 - 8) = 1 `
