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
