Question

what is the structural formula of CLO3 negativeand and NO2

Answer 1

hey mate here is ye answer
H = GA + (VE - V - C)/2 , where H denotes the hybridization number , GA denotes the group atoms attached to the central atom , VE denotes the valence electrons of the central atom , V denotes the valency of the central atom and C denotes the charge over the molecule .

The central atom in ClO3 - is chlorine . It is attached to three oxygen atoms so number of group atoms attached is 3 . The valence electrons over the chlorine atom is 7 and the chlorine atom is attached to three oxygen atoms by means of three double covalent bonds so its valency is 6 . Also there is a negative charge present over the molecule , so its charge is -1 . Putting the values we get

H = 3 + (7 - 6 - (-1))/2

H = 3 + (1 + 1)/2

H = 3 + 2/2

H = 3 + 1

H = 4

So the molecule is having a hybridization number of 4 and thus its hybridization state is sp3 that is the molecule of ClO3 - is sp3 hybridized .

Answer 2

The structural formula of ClO₃⁻ (Chlorate ion) and NO₂ (Nitrogen dioxide) are in the attachment below↓↓
