electronegativity
to attract the tendancy of an atom a bonding pair of electrons in a covalent bond.
Tetrahedral organic compounds
saturated, they have no double/triple bonds.Always 3D
General formula of alkanes
CnH2n+2
Name this compound: C2H4Cl2
1,1-dichloroethane
Physical properties of chloroethanes:
liquid state at room temp (chloro(m)ethane are gas). boiling point higher than alkanes cause of C-CI bonds. Boiling point increases with increasing chain length bc of increasing van der waals forces.
solubility of chloroalkanes
.insolubke in water, solubke in non-polar solvents(cyclohexane)
