CH. 8 Flashcard

Front

Which molecule is linear in shape?

Back

CO2 is linear in shape due to its symmetrical arrangement of atoms.

Front

How many shared pairs of electrons are in a triple bond?

Back

A triple bond has 6 shared electrons, which means there are 3 pairs of shared electrons.

Front

How many lone pair sets does carbon (C) have?

Back

Carbon (C) has 0 lone pair sets in its most common forms.

Front

How many shared electrons are in a double bond?

Back

A double bond has 4 shared electrons, which means there are 2 pairs of shared electrons.

Front

How many shared electrons are in a single bond?

Back

A single bond has 2 shared electrons, which means there is 1 pair of shared electrons.

Front

What is the shape of NH3 (ammonia)?

Back

NH3 has a trigonal pyramidal shape due to the presence of one lone pair on nitrogen.

Front

What is the shape of CH4 (methane)?

Back

CH4 has a tetrahedral shape due to the four bonds formed by carbon.

Front

Define a covalent bond.

Back

A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.

Front

What is the difference between a single, double, and triple bond?

Back

A single bond shares 2 electrons, a double bond shares 4 electrons, and a triple bond shares 6 electrons.

Front

What is a lone pair of electrons?

Back

A lone pair of electrons is a pair of valence electrons that are not shared with another atom.
