CI & SI

S.I. & C.I

Arrange the elements as per the instructions: Na, K, CI, S, Si [increasing order of ionization energy].

B, CI and Ni are:

The SI unit of distance is m, whereas the SI unit of displacement is km.

The CI - C - CI angle in 1, 1, 2, 2 , tetrachloroethone and tetrachloromethane respectively will be about:
