Chemistry Module 5
which atom in the C-CI bond has a partial negative charge
CI
which of the following is the most electronegative atom (C N O F)
F fluorine is the most electronegative
which of the following is an example of a covalent bond (K-CI AI-CI H-CI AI-AI)
H-CI covalent bonds are typically formed between two nonmetals
identify the correct dipole in the C-Br bond in the Lewis Structure of methyl bromide shown using a vector arrow
I
which of the following is not a covalent bond (N-N Mg-N N-O H-H)
Mg-N typically a nonmetal bonded to a nonmetal is a covalent bond
the molecule HI is
heteronuclear because there are two non identical nuclei in the molecule
the compound NaBr is an
ionic compound
which of the following statements is false
linear molecules cannot have a net dipole moment *linear molecules can easily be given the appropriate arrangement of elements
which atom in the Br-F molecule has a partial negative charge (δ−)
F partial charges are determined by the relative electronegativities of the atoms in a molecule; the more electronegative atom
which of the following is an example of an ionic bond ( K-F C-H Kr-H C-F)
K-F the difference in electronegativity is greater than 1.5 and between a metal and a nonmetal
which of the following is an example of an ionic bond (F-F O-F Na-O Na-Na)
Na-O
the reason an ionic bond forms can best be described as
the energy change for an electron transfer results in a large gain in stability when the ionic bond forms
in a covalent bond
two atoms share valence electrons and those shared electrons form the chemical bond
what happens when an ionic bond forms
two atoms, one atom which is more electronegative than the other, exchange electrons and charges hold the atoms together
