The Normal Boiling Point for H Br Is Higher

question 29

Multiple Choice

The normal boiling point for H Br is higher than the normal boiling point for H Cl.This can be explained by

• A)larger dipole-dipole forces for H Br.
• B)larger dispersion forces for H Br.
• C)larger hydrogen-bond forces for H Br.
• D)larger dipole-dipole forces,larger dispersion forces,and larger hydrogen-bond forces for H Br.

Factorial Research

A type of experimental research design that involves multiple independent variables and examines their main effects as well as the interaction effects between them.

Independent Variables

Variables in an experiment that are manipulated or changed to observe their effect on dependent variables.

Combinations

Choosing elements from a broader group without regard to the sequence in which they are selected.

Main Effect

The direct impact of an independent variable on a dependent variable in an experiment.
