SrCl2
The formula for carbon dibromide is CBr2.
As the name suggests the formula is C2Br4 Structurally, thiscould be Br2C=CBr2 ( 1,1,2,2-tetrabromoeth**e**ne) Br2HC-CHBr2 ( 1,1,2,2-tetrabromoeth**a**ne) or Br3C-CH2Br ( 1,1,1,2-tetrabromoeth**a**ne) Note the positioning of the bromine atoms and the one letter difference in the names.
Two possibilities CHBr = CHBr ( 1,2-dibromoethene) This can have two sub-enantiomers; / 'cis'' or 'trans' Where the two bromine atoms are on the same side of the double bond , and is formula ' (z)1,2-dibromoethene. The other being Where the two bromine atoms are on the opposite side of the double bond , and is formula ' (e)1,2-dibromoethene. CH2 = CBr2 ( 1,1- dibromoethene)
