Bonding in which - A: `C Cl_(4)` B: `H_(2)`, C: `HCl` D: `NH_(4)Cl` - involves coordinate bonding.

Which one of H_2 O and HCl is capable of forming coordinate bond?

Choose from the letters A,B,C,D and E, to match the descriptions 1 to 5 given below: , (A) NH_(4)Cl (B) AgCl (C ) PbCl_(2) (D) FeCl_(2) (E ) Ag(NH_(3))_(2)Cl A soluble salt obtained on reaction of a metallic chloride with liquor ammonia.

The C-Cl bond length is shortest in :

Choose from the letters A,B,C,D and E, to match the description given below: , (A) NH_(4)Cl (B) AgCl (C ) PbCl_(2) (D) FeCl_(2) (E ) Ag(NH_(3))_(2)Cl A salt which is insoluble in dilute nitric acid but soluble in ammonium hydroxide.

When NH_(3) is treated with HCl, H-N-H bond angle

On nuclear chlorination, C_(8), H_(10) (A) gives a product (B) which may be oxidised to C_(8) H_(5)O_(4)Cl(C). (A) may alos be chlorinated to give C_(8) H_(8) Cl_(2)(D), C_(8) H_(6)Cl_(4)(E) , and C_(8) H_(4) Cl_(6)(F). (D), (E) and (F) on hydrolysis give halogen-free compounds (G), (H) , and (I) , respectively. With CrCO_(2)Cl_(2), (A) gives C_(8) H_(6)O_(4) which is identiacla with (I) . Identify wtih (I) . Identify the varioius compounds (A) to (J) .

Among LiCl,BeCl_(2), BCl_3 and C Cl_(4) the covalent bond character varies as .

Answer the following : (a) C Cl_(4) is non-polar but CH_(3)Cl is polar. (b) SiF_(4) is non-polar although Si-F bonds are polar. (c ) A hetero-diatomic molecule is always polar.

Which has the highest pH ? (a) NaCl (b) Na_(2)CO_(3) (c) NH_(4)Cl (d) NaNO_(3)
