Halogenation: Addition of elementary bromine or chlorine to alkenes yields vicinal dibromo- and dichloroalkanes, respectively. The decoloration of a solution of bromine in water is an analytical test for the presence of alkenes:

CH2=CH2 + Br2 → BrCH2-CH2Br
similarly
CH=CHCH3 + Cl2 → ClCH2-CClHCH3


Using the simpler of the above examples it is also used as a quantitive test of unsaturation, expressed as the bromine number of a single compound or mixture. The reaction works because the high electron density at the double bond causes a temporary shift of electrons in the Br-Br bond causing a temporary induced dipole. This makes the Br closest to the double bond slightly positive and therefore an electrophile.

AgNO3 + NaCl ==> AgCl + NaNO3 It would not must be balanced from now on. Thats it! i'm doing a lab this night employing that comparable equation! humorous! yet I doubt we are doing an analogous factor.... r u doing Fajan's technique? looking % chloride? whilst you're and you already know the thank you to do it answer my question cuz im stumped... whilst you're no longer and you're at a loss for words, forget what I pronounced and want my answer facilitates!
