The coordinate bond in \(BF_4^-\) can be considered a sigma bonnd.

Q. What is a COORDINATE bond? It is considered a sigma bond or pi bond? If it is sigma then do we consider it for calculation of geometry,shape and hybridisation ?? Also while finding no. of bond pairs of a compound, do we add the no. of coordinate bonds as well?

Q. The outer orbitals of C in ethene molecules can be considered to be hybridized to give three equivalent sp2 orbitals. The total number of sigma and pi bonds in ethene molecule is 1) 1 sigma and 2 pi bonds 2) 3 sigma and 2 pi bonds 3) 4 sigma and 1 pi bonds 4) 5 sigma and 1 pi bonds

Q. 52. Co-ordinate bond is considered as sigma bond or pi bond?

Q. Is coordinate bond equivalent to a double bond or to a single bond? which is to be considered while drawing Lewis structures and calculating formal charge?
