Question

Sigma Bonding Ach Siamo Bonding A o bond arises from the straight-on overlap of two atomic orbitals. The electron density lies along the axis of the two bonded nuclei. sp hybrid orbital Example: Sigma Bonding in methane, CH4 1s orbital What atomic or hybrid orbitals make up the sigma bond between Brand F in bromine pentafluoride, BrFs? orbital on Br + orbital on F What are the approximate F.Br. F bond angles ? (list all possible)

Answer 1

Shape What atomic or hybrid orbitals make up the sigma bond between Brand & in bromine pentafuoride Brts. Here Brfs, Bo has hybridisation 883 d². so. [8P2d" bybrid Torbital on Br+ borbital Brfs has octabe oral geometry in Sanare pyramidal In Sanare pramidal structure youwill think that all the bonds will be goo but its completely opposite here as none of the angle istruly go The reason being that there is a lone pair on the Central Brakom due to repulsion between electron pair over Br and fluorine bond the geometry gets distorted and angles now become less than 90° almost 88° Dichloro etuglene has strechure as follows hence T8p2 hybrid) orbital or G + [8p² hybrid orbital on la nom There are 5 s bonds present in dichbroefhylene There are 1 + bond present in dichloroethylene.
