Study Notes
Multiple Choice Questions
- Question 1: The correct answer is c. 2
- HSO3-1 has two double bonds, or pi bonds, in its structure.
- Question 2: The correct answer is b. In a 100 g sample 61 g is chloride
- Sodium chloride is 39% sodium by mass, leaving 61% for chlorine.
- Question 3: The correct answer is a. Tetrahedral
- sp3 hybridization leads to a tetrahedral electron pair geometry.
- Question 4: The correct answer is a. Ionic Bond
- An ionic bond forms when a positively charged ion (cation) is attracted to a negatively charged ion (anion).
- Question 5: The correct answer is b. 60.06 g/mole
- The empirical formula for Ribose is CH2O, which has a molar mass of 60.06 g/mole.
- Question 6: The correct answer is a. Hybridization
- Hybridization theory explains how carbon can bond to four hydrogens in methane (CH4) by mixing atomic orbitals to create hybrid orbitals.
- Question 7: The correct answer is b. Two non-metals
- Most covalent bonds form between two non-metals because they have similar electronegativity values.
- Question 8: The correct answer is a. Boron
- Boron has only 3 valence electrons, so it can only form 3 bonds, violating the octet rule.
- Question 9: The correct answer is c. Endothermic
- When the enthalpy of a reaction is positive, energy is absorbed, and the reaction is endothermic.
- Question 10: The correct answer is d. Nonpolar covalent
- A nonpolar covalent bond forms when the electronegativity difference between two atoms is less than 0.4.
- Question 11: The correct answer is a. Square Pyramid
- BrF5 has a square pyramidal molecular geometry based on its 5 bonding pairs and 1 lone pair of electrons around the central bromide atom.
- Question 12: The correct answer is b. Water
- Water is soluble in methanol (CH3OH) due to their ability to form hydrogen bonds.
- Question 13: The correct answer is c. BF3
- Boron trifluoride (BF3) does not go to the excited state before hybridizing. The boron atom's 2s and 2p orbitals hybridize to form three sp2 orbitals, which are used for bonding with the fluorine atoms.
