Dichloroethylene (C2H2Cl2) has three forms (isomers), each of which is a different substance. (b) Which of these isomers has a zero dipole moment?

For each statement, indicate whether it is true or false. (a) In order to make a covalent bond, the orbitals on each atom in the bond must overlap. (b) A p orbital on one atom cannot make a bond to an s orbital on another atom.

Step 1: Understand the concept of covalent bonding. Covalent bonds are formed when two atoms share electrons. This sharing occurs through the overlap of atomic orbitals, which allows the electrons to be shared between the atoms.
Step 2: Analyze statement (a). Consider the requirement for orbital overlap in covalent bonding. Since covalent bonds involve the sharing of electrons through overlapping orbitals, determine if the statement about the necessity of orbital overlap is true or false.
Step 3: Understand the types of orbitals involved in bonding. Orbitals such as s, p, d, and f can participate in bonding. The s orbital is spherical, while p orbitals are dumbbell-shaped, and they can overlap with each other or with other types of orbitals.
Step 4: Analyze statement (b). Consider whether a p orbital on one atom can overlap with an s orbital on another atom. Recall that different types of orbitals can indeed overlap to form bonds, such as the overlap between an s orbital and a p orbital, which is common in many molecules.
Step 5: Evaluate the truth of each statement based on your understanding of orbital overlap and bonding. Use your knowledge of how different orbitals can interact to determine the truth value of each statement.
