The compound MX is tetrahedral. The number of XMX angles in the compound is:

CHEMICAL BONDING 3 It is a tetrahedral therefore number of X-M-X angle will be 6. 10. Which of the following are isoelectronic and isostructural? 2 3 3 3 3 NO , CO ,ClO , SO (a) 2 3 3 NO , CO (b) 3 3 SO , NO (c) 2 3 3 ClO , CO (d) 2 3 3 CO , SO Isoelectronic species are those species that have the same number of electrons while iso-structural species are those species that have the same shape. 3 NO 32 electrons 2 3 CO 32 electrons 3 ClO 42 electrons 3 SO 41 electrons Even, the structure of 3 NO and 2 3 CO have trigonal planar geometry and hence they are isoelec
