Question 2.
a) Doublet will appear
Explanation: Phosphorus couples with 29Si, multiplicity of the signal = 2nI + 1 = 2*1*1/2 + 1 = 2 (doublet).
b) Quartet of doublet will appear
Explanation: Phosphorus first couples with equatorial 19F, multiplicity of the signal = 2nI + 1 = 2*3*1/2 + 1 = 4 (quartet), followed by coupling with axial19F, multiplicity of the signal = 2nI + 1 = 2*1*1/2 + 1 = 2 (doublet). Hence, each line of the quartet will further split into doublet, i.e. quartet of doublet.
c) Quartet of triplet will appear
Explanation: Phosphorus first couples with equatorial 19F, multiplicity of the signal = 2nI + 1 = 2*3*1/2 + 1 = 4 (quartet), followed by coupling with 1H, multiplicity of the signal = 2nI + 1 = 2*2*1/2 + 1 = 3 (triplet). Hence, each line of the quartet will further split into triplet, i.e. quartet of triplet.
d) Sextet (at room temperature); quartet of triplet (at low temperature) will appear.
Explanation: At room temperature, all the five F's undergo rapid exchange from axial to equatorial, hence the multiplicity of the signal = 2nI + 1 = 2*5*1/2 + 1 = 6 (sextet). At low temperature such as -78oC, phosporus first couple with equatorial 19F, multiplicity of the signal = 2nI + 1 = 2*3*1/2 + 1 = 3 (quartet), followed by coupling with axial 19F, multiplicity of the signal = 2nI + 1 = 2*2*1/2 + 1 = 3 (triplet). Hence, each line of the quartet will further split into triplet, i.e. quartet of triplet.
e) Dectet will appear.
Explanation: Phosphorus couples with 19F, multiplicity of the signal = 2nI + 1 = 2*9*1/2 + 1 = 10 (dectet).
