Chapter 1: Problem 24

Judging from their relative positions in the Periodic Table, which atom in each set is more electronegative? (a) Carbon or nitrogen (b) Chlorine or bromine (c) Oxygen or sulfur

Short Answer

Expert verified
Short Answer: (a) Nitrogen is more electronegative than carbon. (b) Chlorine is more electronegative than bromine. (c) Oxygen is more electronegative than sulfur.

Step by step solution

01

(a) Carbon or nitrogen

Based on the Periodic Table, carbon (C) is in group 14 (IVA) and period 2, while nitrogen (N) is in group 15 (VA) and period 2. Since electronegativity increases across a period from left to right, nitrogen is more electronegative than carbon.
02

(b) Chlorine or bromine

Looking at the Periodic Table, chlorine (Cl) is in group 17 (VIIA) and period 3, while bromine (Br) is in group 17 (VIIA) and period 4. Since electronegativity decreases down a group, chlorine is more electronegative than bromine.
03

(c) Oxygen or sulfur

From the Periodic Table, oxygen (O) is in group 16 (VIA) and period 2, while sulfur (S) is in group 16 (VIA) and period 3. As electronegativity decreases down a group, oxygen is more electronegative than sulfur.

What is the meaning of the term tertiary \(\left(3^{\circ}\right)\) when it is used to classify amines? Draw a structural formula for the one tertiary \(\left(3^{\circ}\right)\) amine known as Hünig's base (N,N-diisopropylethylamine).

In future chapters, we will encounter carbanions-ions in which a carbon atom has three bonds and a lone pair of electrons and bears a negative charge. Draw another contributing structure for the allyl anion. Now using cartoon representations, draw the three orbitals that represent the delocalized \(\pi\) system (look at Figure \(1.26\) for a hint). Which of the three orbitals are populated with electrons?

Draw a Lewis structure for methyl isocyanate, \(\mathrm{CH}_{3} \mathrm{NCO}\), showing all valence electrons. Predict all bond angles in this molecule and the hybridization of each \(\mathrm{C}, \mathrm{N}\), and \(\mathrm{O}\).

In what kind of orbitals do the lone-pair electrons on the oxygen of acetone reside? Are they in the same plane as the methyl \(-\mathrm{CH}_{3}\) groups, or are they perpendicular to the methyl \(-\mathrm{CH}_{3}\) groups?

Tetrafluoroethylene, \(\mathrm{C}_{2} \mathrm{~F}_{4}\) is the starting material for the synthesis of the polymer polytetrafluoroethylene (PTFE), one form of which is known as Teflon. Tetrafluoroethylene has a dipole moment of zero. Propose a structural formula for this molecule.
