Cinnamaldehyde is a naturally-occurring compound that has a conjugated system penta-1,3-diene is a molecule with a conjugated system Diazomethane conjugated pi-system. In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability.
The Board is headed by a full-time Chairman whose term lasts three years and who technically reports to the Secretary of School Education in the Government of Punjab.The current Education Secretary of the board is IAS Sh Harsant Singh sekhon who is sincerely committed to shape the education system of Punjab by his pioneering Initiatives like ...
A conjugated 1,4 addition using a Gilman reagent with an arbitrary R group. These reagents are useful because, unlike related Grignard reagents and organolithium reagents, they react with organic halides to replace the halide group with an R group (the Corey–House reaction). Such displacement reactions allow for the synthesis of complex ...

DOTA (also known as tetraxetan) is an organic compound with the formula (CH 2 CH 2 NCH 2 CO 2 H) 4. The molecule consists of a central 12-membered tetraaza (i.e., containing four nitrogen atoms) ring. DOTA is used as a complexing agent, especially for lanthanide ions. Its complexes have medical applications as contrast agents and cancer treatments.
