Pre-AP CHEM Unit 6 Day 2 Review

Which of the following bonds would be the shortest?

• A
• B
• C
• D

In general, a double bond is _____ than a single bond between a given pair of atoms.

• more polar
• less polar
• stronger
• weaker

Given that elements O and H are bonded and the electronegativity difference is 1.4, determine the bond type and the more-negative atom.

• polar-covalent bond; O
• nonpolar-covalent bond; O
• polar-covalent bond; H
• nonpolar-covalent bond; H

On the usual Pauling scale of electronegativities, the electronegativity of Selenium (Se) is 2.4, while that of chlorine (Cl) is 3.0. Based on these values we should expect the bondingbetween Se and Cl to be

• ionic
• covalent and nonpolar
• covalent and polar with the Se end of the bond slightly negative
• covalent and polar with the Cl end of the bond slightly negative

The compound PI₃ has what IUPAC name?

• potassium iodide
• phosphorus iodide
• phosphorus triiodide
• potassium triiodide

Choose the pair of names and formulas that do NOT match.

• Cl₂O₇ : dichlorine heptoxide
• NO : nitrogen monoxide
• N₂O₅ : dinitrogen pentoxide
• SO₃ : monosulfur trioxide

Covalent compounds involve a _________ of electrons and typically involve atoms that have _________ electronegativities.

• sharing; 
  similar
• sharing;
  very different
• transfer;
  similar
• transfer;
  very different

The electronegativity of an atom generally _______ going down columns and _______ going left to right across rows. An element like fluorine would most likely form a(n) _______ bond with an element like oxygen.

• decreases;
  increases;
  ionic
• decreases;

Materials that conduct heat and electricity well in the solid state result when:

• metals bond with metals
• metals bond with non-metals
• non-metals bond with non-metals
• any type of element bonds with any other
