Which of the following compounds is least likely to give effervescence of CO2\mathrm{CO}_2 in presence of aq. NaHCO3\mathrm{NaHCO}_3 ?Which of the following compounds is least likely to give effervescence of CO_2 in presence of aq. NaHCO_3 ?Which of the following compounds is least likely to give effervescence of CO_2 in presence of aq. NaHCO_3 ?Which of the following compounds is least likely to give effervescence of CO_2 in presence of aq. NaHCO_3 ?Which of the following compounds is least likely to give effervescence of CO_2 in presence of aq. NaHCO_3 ?

Options

  1. ALet P be the foot of the perpendicular from the point Q(10,-3,-1) on the line (x-3)/(7)=(y-2)/(-1)=(z+1)/(-2) . Then
  2. BLet P be the foot of the perpendicular from the point Q(10,-3,-1) on the line (x-3)/(7)=(y-2)/(-1)=(z+1)/(-2) . Then
  3. CLet P be the foot of the perpendicular from the point Q(10,-3,-1) on the line (x-3)/(7)=(y-2)/(-1)=(z+1)/(-2) . Then
  4. DLet P be the foot of the perpendicular from the point Q(10,-3,-1) on the line (x-3)/(7)=(y-2)/(-1)=(z+1)/(-2) . Then

Correct answer

D. Let P be the foot of the perpendicular from the point Q(10,-3,-1) on the line (x-3)/(7)=(y-2)/(-1)=(z+1)/(-2) . Then

Step-by-step solution

Concept - Those compounds which are more acidic than H2CO3\mathrm{H}_2 \mathrm{CO}_3 can gives effervescence of CO2\mathrm{CO}_2 with aq. NaHCO3\mathrm{NaHCO}_3.
Release CO2↑\mathrm{CO}_2 \uparrow gas with aq. NaHCO 3
⇒[ A.S. ]Comp. >[ A.S. ]H2CO3\Rightarrow[\text{ A.S. }]_{\text{Comp. }} \gt [\text{ A.S. }]_{\mathrm{H}_2 \mathrm{CO}_3}
→\rightarrow Option 1,2 and 3 gives effervescence of CO2\mathrm{CO}_2 gas with NaHCO3\mathrm{NaHCO}_3
→\rightarrow Option (4) Not gives CO2\mathrm{CO}_2 gas with NaHCO3\mathrm{NaHCO}_3.
