The correct order of increasing bond angles in the following triatomic species is NO2+<NO2<NO2−NO_2^+ < NO_2 < NO_2^- NO2+<NO2−<NO2NO_2^+ < NO_2^- < NO_2 NO2−<NO2+<NO2NO_2^- < NO_2^+ < NO_2 NO2−<NO2<NO2+NO_2^- < NO_2 < NO_2^+

Multiple Choice Options

  • A adenine and guanine; thymine and cytosine
  • B uracil and adenine; cytosine and guanine
  • C adenine and thymine; guanine and cytosine
  • D adenine and thymine; guanine and uracil.

Step-by-Step Verified Solution

DNA contains two types of nitrogeneous bases Purine _ Adenine (A) and guanine (G) Pyrimidine _ Cytosine (C) and thymine (T) The purine and pyrimidine bases pair only in certain combination. Adenine pairs with thymine (A : T) by two hydrogen bonds and guanine with cytosine (G : C) by three hydrogen bonds.
