Answer: The ratio of carbon to bromine atoms in the molecule is 3:1
Explanation:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions.
Chemical formula shows the elements in a compound and the relative proportions of those elements.
The chemical formula given for the compound is which means the ratio of carbon to bromine atoms is 3: 1.
Thus the ratio of carbon to bromine atoms in the molecule is 3:1

Answer: The order from weakest to strongest is:
Explanation:
Dispersion force is the weakest intermolecular force. It is a temporary attractive force that come into action when the electrons in two neighboring atoms are at the positions which results in formation of temporary dipoles.
Dipole interaction is an attractive interaction between the positive end and negative end of the polar molecule.
Hydrogen bond is a weak bond between two adjacent molecules due to an electrostatic attraction between a hydrogen atom in a molecule with an electronegative atom of an adjacent molecule.
Single covalent bond is more stronger bond than the the interaction stated above because there is sharing of an electron between two atoms.
Ionic bond is the strongest bonds in which complete transfer of electrons is present. Due to high electronegativity difference between the bonded atoms there is a high electrostatic interaction between the oppositely charged ions which makes ionic bond strongest from all the other types of the bonds.
So, the order is:
