what is dipole moment of 1,1-Dibromoethene
1,2,dibromoethene
There are (in total) 8 structural isomers of C5H11Br, from the 3 different 'pentanyl' hydrocarbon (-C5H11) isomers (n-pentane, iso-pentane and neo-pentane):3x in n-pentane: 1-, or 2-, or 3-Bromo-pentane4x in isopentane: 1-, or 2-, or 3-, or 4-Bromo-Methyl-butane1x in neopentane: 1-Bromo-diMethyl-propane
Yes, it's possible. Cis: Br/H=Br/H or Trans: Br/H=H/Br
It's dichloroetheneNote to initial responder: if it was dichloroethane as you said originally, then the formula would be C2H4Cl2.
There are numerous possible constitutional isomers of bromopentane. Specifically, the bromine atom can be attached to any of the carbon atoms (although there are only three unique possibilities because the 2 end carbons are identical). So you could have:1-bromopentane (same molecule as 5-bromopentane, but lower number is used)2-bromopentane (same molecule as 4-bromopentane, but lower number is used)3-bromopentaneThen you can also have different connectivity between the carbon atoms. So pentane can either be normal pentane (5 carbons in a row), or it can be a branched structure. There are two possible branched structures for pentane: 2-methylbutane ("isopentane") and 2,2-dimethylpropane ("neopentane").For 2-methylbutane the possibilities are:1-bromo-2-methylbutane2-bromo-2-methylbutane2-bromo-3-methylbutane (bromine takes precedence and gets the lower number)1-bromo-3-methylbutaneFinally, there's only one possibility for 2,2-dimethylpropane, since the four methyl groups are equivalent and the central carbon is already bonded to four other things:1-bromo-2,2-dimethylpropane
