Hydrogen typically forms only one bond in a molecule, so it is not a central atom in Lewis structures because it does not have the capacity to bond with multiple atoms simultaneously. Fluorine, on the other hand, is a highly electronegative element and prefers to form single bonds in compounds, making it unlikely to be a central atom in a Lewis structure where it would need to form multiple bonds. Central atoms in Lewis structures are typically elements that can form multiple bonds and expand their valence shell, such as carbon, nitrogen, and oxygen.
Hydrogen and fluorine can form multiple bonds, such as in the case of hydrogen fluoride (HF), which has a covalent bond where fluorine shares one electron with hydrogen. This bond is strong due to the high electronegativity of fluorine.
Yes, fluorine is more electronegative than hydrogen : it has the highest elemental electronegativity by the Allen method, at 4.193 to hydrogen's 2.300 (only neon is higher than fluorine, but it cannot be calculated using Pauling units because it forms no ordinary compounds).
No, the compound CH3CH2CH2CH3 (butane) does not have any hydrogen atoms bonded to electronegative atoms such as oxygen, nitrogen, or fluorine. Therefore, it cannot form hydrogen bonds.
No, CH4 does not have hydrogen bond. Hydrogen bonding occurs when hydrogen is bonded to highly electronegative elements like oxygen, nitrogen, or fluorine, which is not the case in CH4 where hydrogen is bonded to carbon.
No, CHCl3 (chloroform) cannot participate in hydrogen bonding because it does not contain any hydrogen atoms bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine. Hydrogen bonding occurs when hydrogen atoms are directly attached to these electronegative atoms.

A hydrocarbon with all the hydrogen atoms replaced with either chlorine atoms or fluorine atoms. They cannot be all chlorine or all fluorine atoms, but must be some mixture.
No, the compound CH3CH2CH2CH3 (butane) does not have any hydrogen atoms bonded to electronegative atoms such as oxygen, nitrogen, or fluorine. Therefore, it cannot form hydrogen bonds.
No, CH4 does not have hydrogen bond. Hydrogen bonding occurs when hydrogen is bonded to highly electronegative elements like oxygen, nitrogen, or fluorine, which is not the case in CH4 where hydrogen is bonded to carbon.
No, C3H8 (propane) cannot form hydrogen bonds because it lacks any hydrogen atoms directly bonded to highly electronegative elements like oxygen, nitrogen, or fluorine, which are essential for hydrogen bonding.
No, CHCl3 (chloroform) cannot participate in hydrogen bonding because it does not contain any hydrogen atoms bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine. Hydrogen bonding occurs when hydrogen atoms are directly attached to these electronegative atoms.
Benzene cannot form hydrogen bonds because it does not have hydrogen atoms bonded directly to highly electronegative atoms like nitrogen, oxygen, or fluorine. Benzene has only carbon and hydrogen atoms, so it does not exhibit hydrogen bonding.
No, BeH2 cannot form a hydrogen bond because it does not contain hydrogen atoms bonded to electronegative atoms such as oxygen, nitrogen, or fluorine, which are necessary for hydrogen bond formation. Instead, BeH2 forms ionic bonds between beryllium and hydrogen atoms.
There are no isomers for HF (hydrogen fluoride) because it is a simple diatomic molecule composed of one hydrogen atom and one fluorine atom. Its structure is linear and cannot be rearranged to form isomers.
No, Ch3-O-CH3 (dimethyl ether) cannot form hydrogen bonds. Hydrogen bonding requires a hydrogen atom bonded to an electronegative atom such as oxygen, nitrogen, or fluorine. In dimethyl ether, both of the carbon atoms are bonded to oxygen, not hydrogen.
Chlorine cannot form a hydrogen bond only Nitrogen, Oxygen, and Flourine can
