Question

question 5 (1 point) molecules or ions with a tetrahedral shape include which of the following? i. cf4 ii. scl4 iii. nh4+ i. only ii. only i.,ii., and iii. i. and iii. only i. and ii. only

Explanation:

CF₄ has a central carbon atom bonded to four fluorine atoms with no lone - pairs on the central atom, giving it a tetrahedral shape. SCl₄ has a central sulfur atom bonded to four chlorine atoms and one lone - pair on the sulfur, resulting in a seesaw shape. NH₄⁺ has a central nitrogen atom bonded to four hydrogen atoms with no lone - pairs on the central atom, giving it a tetrahedral shape. So, CF₄ and NH₄⁺ have tetrahedral shapes.

Answer:

i. and iii. only
