Question

consider the carbon tetrachloride (ccl4) molecule. what is the central atom? enter its chemical symbol. how many lone pairs are around the central atom? what is the ideal angle between the carbon - chlorine bonds? compared to the ideal angle, you would expect the actual angle between the carbon - chlorine bonds to be...

Explanation:

Step1: Identify central atom

In $CCl_4$, carbon is central. Its symbol is C.

Step2: Determine lone - pairs

Carbon in $CCl_4$ has 4 bonding pairs and 0 lone pairs as it forms 4 single bonds with chlorine atoms.

Step3: Find ideal bond - angle

$CCl_4$ has a tetrahedral geometry. The ideal bond - angle in a tetrahedral molecule is 109.5°.

Step4: Compare ideal and actual angles

Since there are no lone - pairs to cause repulsion, the actual angle between carbon - chlorine bonds is equal to the ideal angle.

Answer:

What is the central atom? Enter its chemical symbol: C
How many lone pairs are around the central atom? 0
What is the ideal angle between the carbon - chlorine bonds? 109.5
Compared to the ideal angle, you would expect the actual angle between the carbon - chlorine bonds to be: equal to the ideal angle
