çift bağ

التركية - الإنجليزية

تعريف çift bağ في التركية الإنجليزية القاموس.

double bond

A covalent bond in which two electron pairs (instead of the usual one) are shared between two atoms; most common between carbon atoms and carbon, oxygen or nitrogen atoms, but several other forms are known

Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms

Two atoms sharing electrons as in a °single bond (that is, a °sigma bond) may also share electrons in an orbital with a node passing through the two atoms This adds a second, weaker bonding interaction (a °pi bond); the combination is termed a double bond A twisting motion that forces the nodal plane at one atom to become perpendicular to the nodal plane on the other atom eliminates the (signed) °overlap between the atomic orbitals, destroying the pi bond The energy required to do this creates a large barrier to rotation about the bond (see °triple bond)

a covalent bond in which two pairs of electrons are shared between two atoms

a bond in which two pairs of electrons are shared by two atoms (13 8)

a bond in which two pairs of electrons are shared between two atoms

A covalent bond in which two electron pairs are shared between two atoms

A covalent bond consisting of one sigma (s) bond and one pi (p) bond

{i} covalent bond, chemical bond formed by shared electrons

A structure formed when adjoining carbon atoms in the carbon chain of a saturated fatty lose two hydrogen atoms Double bonds may be either in the cis or trans orientation

When an atom is bonded to another atom by two sets of electron pairs Back to top E

a covalent bond composed of two pairs of shared electrons
