Carbon
A carbon atom can form up to 4 covalent bonds with other atoms. This is because carbon has four valence electrons in its outer shell, allowing it to share electrons with other atoms in order to complete its octet.
Silicon dioxide (SiO2) would exhibit the greatest amount of covalent bonding among the compounds listed. This is because silicon (Si) and oxygen (O) have a higher electronegativity difference, leading to stronger covalent bonds. Al2O3 and OF2 also have some covalent bonding, but it is not as strong as in SiO2.
Covalent bonds themselves are not soluble in water because they are intramolecular bonds within compounds. However, some covalent compounds can be soluble in water depending on their polarity and ability to form hydrogen bonds with water molecules.
yes
The dielectric constant of covalent compounds is low because they have strong covalent bonds that do not allow for easy separation of charges when exposed to an electric field. This limits the ability of these compounds to induce an electric field within themselves and therefore results in a low dielectric constant.
HYDROGEN
Kerosene is saturated, because it only contains single carbon-carbon covalent bonds. Kerosene is actually a mixture of more than one straight-chain or branched alkane hydrocarbons, but none of them feature double or triple bonds, so the Lewis structure indicates it is saturated.
A carbon atom can form up to 4 covalent bonds with other atoms. This is because carbon has four valence electrons in its outer shell, allowing it to share electrons with other atoms in order to complete its octet.
Branched chain hydrocarbons have a lower tendency to knock compared to straight-chain hydrocarbons due to their increased resistance to autoignition. Ring hydrocarbons, such as aromatics, also have lower knock tendencies because of their stable structures. Overall, both branched chain and ring hydrocarbons are preferred in high-performance engines to reduce knocking.

yes
No because it is a branched molecule.
covalent because it is made up of only nonmetal elements
The dielectric constant of covalent compounds is low because they have strong covalent bonds that do not allow for easy separation of charges when exposed to an electric field. This limits the ability of these compounds to induce an electric field within themselves and therefore results in a low dielectric constant.
An oxygen atom with a negative charge can form two covalent bonds. This is because oxygen normally forms two covalent bonds to achieve a stable electron configuration, and the negative charge does not affect its ability to form bonds.
Hydrogen can only form one covalent bond because it only has one electron.
