Identify the correct statement (s)?
A) I-Cl bond is stronger than Br-Br bond
B) I-Cl is polar where as Br-Br is non-polar
C) \(SnCl_{4}\) more covalent than \(SnCl_{2}\)
D) \(O_{2}F_{2}\) oxidises Pu to \(PuF_{6}\)

Which of the following statements are correct? 1. A sigma bond is stronger than a pi bond 2. A covalent bond is stronger than a hydrrogen bond 3. HF is more polar than HCl 4. There is one electrovalent bond and three covalent bonds in methylene chloride Select the correct answer using the codes given below

Account for the following : (i) Sulphur in vapour from exhibits paramagnetic behavious. (ii) SnCl_(4) is more covalent the SnCl_(2) . (iii) H_(3)PO_(2) is a stronger reducing agent then H_(3)PO_(3) .

Phenol reacts with Br_2 in C Cl_4 at low temp. to give

The number of covalent bonds in C_(4)H_(7)Br_(2) is -

Assertion: n- Buty chloride has higher boiling point than n-butyl bromide Reason C-CI bond is more polar than C-Br bond .
