Question

to support your answer.

1. predict the polarity of the following molecules/lons. justify your prediction.

a. no, ion.
b. cobr,

completion - complete each statement.

1. the shape of sulfur dioxide would most likely be
2. the shape of sulphur hexachloride, scl, is
3. the shape of methane, ch, is
4. the shape of ammonia, nh, is
5. the shape of boron trihydride, bh, is

Explanation:

1. Sulfur dioxide (SO₂) has a central S atom with 2 bonding pairs and 1 lone pair, leading to a bent shape.
2. Sulfur hexachloride (SCl₆) has a central S atom with 6 bonding pairs and no lone pairs, forming an octahedral shape.
3. Methane (CH₄) has a central C atom with 4 bonding pairs and no lone pairs, resulting in a tetrahedral shape.
4. Ammonia (NH₃) has a central N atom with 3 bonding pairs and 1 lone pair, giving a trigonal pyramidal shape.
5. Boron trihydride (BH₃) has a central B atom with 3 bonding pairs and no lone pairs, leading to a trigonal planar shape.

Answer:

1. bent
2. octahedral
3. tetrahedral
4. trigonal pyramidal
5. trigonal planar
