Answer 2

Answer:

Among the given options species which are isoelectronic and have same bond order are option(b) BF3, So3^2- and CO2^2-

Explanation:

Given: Number of species are given in options(a) to (d).

To Find: Which among the given options has species that are isoelectronic to each other and have same bond angle.

Solution: Isoelectronic species are those species which has same number of electrons either in  bonded state or in free state. Iso means same so species with same number of electrons are isoelectronic.

Bond order can be defined as difference in bonds and anti-bonds in a particular compound or species.

For option (b) BF3 boron has 5 electrons in valence shell in which three are bonded to fluorine atoms and for fluorine it is one electron short of its octet fluorine has total 7 electrons in valence shell. In total the compound BF3 has 3x7= 21 electrons for fluorine and 5 of boron electrons, hence total 26 electrons. The bond order of BF3 is 1.33 as total resonating structures are 4 with one double bond and two single bond

For SO3^2- number of electrons are 26 as sulphur and oxygen belong  to group 16 so both have 6 electrons in its valence shell so electrons of sulphur is 6 and for oxygen electrons are 3x6 = 18 that is total 24 with -2 charge counted as two electrons so total electrons are 26 electrons. Bond order of SO3^2- is 1.33 as it has four sigma bonds and 2 pie bonds.

For CO3^2- the number of electrons is 26 and bond order is 1.33 as there are 3 resonating structure.

So correct option is (b)
