Chapter 5, Problem 5.11P
Interpretation Introduction

(a)

Interpretation: The group with higher priority from the given pair is to be identified.

Concept introduction: The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority. However, in case of isotopes, the atomic number is same but the mass number is different. The isotope with higher mass number is given higher priority.

Answer to Problem 5.11P

The priority of ethyl group (CH2CH3) is higher than the methyl group (CH3).

Explanation of Solution

The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority. In methyl group (CH3), carbon atom is bonded to three hydrogen atoms and in ethyl group (CH2CH3), carbon atom is bonded to two hydrogen atoms and one carbon atom. The atomic mass of carbon is more than hydrogen. Therefore, the higher priority is given to ethyl group (CH2CH3) than methyl group (CH3).

Conclusion

The higher priority is given to ethyl group (CH2CH3) than methyl group (CH3).

Answer to Problem 5.11P

The higher priority is given to group I than group Br.

Explanation of Solution

The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority. The atomic number of Iodine group (I) is 53 and the atomic number of Bromine group (Br) is 35. Therefore, the higher priority is given to group I than group Br.

Conclusion

The higher priority is given to group I than group Br.

Answer to Problem 5.11P

The higher priority is given to group D than group H.

Explanation of Solution

The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority. However, in case of isotopes, the atomic number is same but the mass number is different. The isotope with higher mass number is given higher priority.

The mass number of group H is 1 whereas the mass number of D is 2. Therefore, the higher priority is given to D than H.

Conclusion

The higher priority is given to group D than group H.

Interpretation Introduction

(d)

Answer to Problem 5.11P

The higher priority is given to group CH2Br than group CH2CH2Br.

Explanation of Solution

The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority.

In group CH2CH2Br, the first carbon atom is bonded to another carbon atom whereas in group CH2Br, carbon atom is bonded to Br. The atomic number of Br is more than carbon atom. Therefore, the higher priority is given to group CH2Br than CH2CH2Br

Conclusion

The higher priority is given to group CH2Br than group CH2CH2Br.

Answer to Problem 5.11P

The higher priority is given to group CH2CH2Cl than group CH2CH(CH3)2

Explanation of Solution

The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority.

The second carbon atom of group CH2CH2Cl and CH2CH(CH3)2 is bonded to chlorine and carbon atom, respectively. The atomic number of chlorine is 17 and the atomic number of carbon is 6. Hence, the atomic number of chlorine is more than the atomic number of carbon. Therefore, the higher priority is given to group CH2CH2Cl than group CH2CH(CH3)2.

Conclusion

The higher priority is given to group CH2CH2Cl than group CH2CH(CH3)2.

Answer to Problem 5.11P

The higher priority is given to group CHO than group CH2O.

Explanation of Solution

The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority.

The carbon atom of group CHO and group CH2O is bonded to oxygen atom by double and single bond respectively. When a carbon atom is bonded to oxygen atom by double bond then it is assumed that two oxygen atoms are attached to carbon atom. Hence, in group CHO, the carbon is attached with two oxygen atom. The atomic number of oxygen is more than the atomic number of carbon. Therefore, the higher priority is given to group CHO than group CH2O.

Conclusion

The higher priority is given to group CHO than group CH2O.
