Can't tell you, because they really DO exist: in methane (CH4) and other alkanes all C atoms have four covalent bonds with H and/or other C atoms.
Covalent
The type of bond in which two atoms share electrons is called a covalent bond.
Yes, a peptide bond is a covalent bond.
NO has a covalent bond. Electrons are shared.
That is ionic bonding as well.
covalent bond
Covalent bond can exist in any type of compounds.
A covalent bond
Covalent bond
The covalent compounds do not exist as ions but they exist as moleculesThey exist at room temperature, as liquids or gases. However, a few compounds also exist in the solid state e.g. urea, sugar, etc.The melting and boiling points of covalent compounds are generally lowCovalent compounds are generally insoluble or less soluble in water and in other polar solventsThese are poor conductors of electricity in the fused or dissolved stateSince the covalent bond is localized in between the nuclei of atoms, it is directional in natureA covalent bond can be formed in different ways. When a bond is formed by mutual sharing of one pair of electrons it is known as a 'single covalent bond', or simply 'a single bond'. When a bond is developed due to mutual sharing of more than one pairs of electrons it is termed as 'multiple covalent bond'. Such bonds can be a double covalent bond or a triple covalent bond.
The bond between O and F would be a covalent bond (dative/coordinate), if in fact OF existed. More likely it would exist as OF2 (still covalent bonds).
With itself. Molecular bonding theory and the bond order show a sigma pi discrepancy ( bonding/anti-bonding ) that disallows this tetra-covalent carbon to carbon interaction. Google this for a fuller explanation.
