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_2F_2` oxidises `Pu` to `PuF_6`

Assertion: F-F bond in F_2 is stronger than Cl-Cl bond in Cl_2 Reason: F atom is small in size than.

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) .

A : CBr_(4) is thermally more stable than Cl_(4) . R : C- Br bond energy is more than C-l

Assertion :- Bond Dissociation energy is F_(2) gt Cl_(2) Reason:- Cl_(2) have more electronic repulsion than F_(2) .

(a). If both (A) and (R) are correct and (R) is the correct explanation for (A). (b). If both (A) and (R) are correct and (R) is the correct explanation for (A). (c). If (A) is correct and (R) is incorrect. (d). If (A) is incorrect and (R) is correct. (e). If both (A) and (R) are incorrect. Q. Assertion (A): In organic layer test, Cl_2 water is added to the sodium extract, which oxidises Br^(-) and I^(-) ions to Br_2 and I_2 , respectively. Reason (R): Reduction potential of Cl_2 is greater than that of Br_2 and I_2 .

Cl_(2 is stronger ………………….. agent then Br_(2) and I_(2) as its reduction potential is ……………………… than that of Br_(2) and I_(2)

The correct sequence of bond enthalpy of C-X 'bond is : CH_(3)-F,CH_(3)-Cl,CH_(3)-Br,CH_(3)-I

Which bond is stronger in each of the following cases and why? a. H_(2),Br_(2) , b. O_(2),N_(2) , c. F_(2),Cl_(2)

Statement-1: The O-O bond length in H_(2)O_(2) is longer than that of O_(2)F_(2) . Statement-2: H_(2)O_(2) is a polar covalent molcule.
