Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices provided. (1) Both tetrahedral and trigonal pyramidal molecules have four VSEPR electron groups about the central atom.
(2) The greater the electronegativity difference between two bonded atoms the greater the polarity of the bond between the two atoms.
(3) A double covalent bond between two atoms is approximately twice as strong as a single covalent bond between the same two atoms.

(1) Both tetrahedral and trigonal pyramidal molecules have four VSEPR electron groups about the central atom - This statement is true as both tetrahedral and trigonal pyramidal molecules have four electron groups around the central atom. 
(2) The greater the electronegativity difference between two bonded atoms the greater the polarity of the bond between the two atoms - This statement is true as a greater electronegativity difference results in a stronger dipole moment and thus a greater difference in polarity. 
(3) A double covalent bond between two atoms is approximately twice as strong as a single covalent bond between the same two atoms - This statement is true as a double bond involves 2 highly localized shared electron pairs, making it stronger than a single bond that only involves 1 shared electron pair. Therefore, all three statements are true.
