Two equimolar water solutions of calcium chloride (A) and fructose (B) have: The same osmotic pressure The osmotic pressure of A is higher than that of B The same fusion point The osmotic pressure of A is lower than that of B Considering that the angles of a regular pentagon are 108, why is cyclopentane not planar? The five C-C bonds have eclipsing strain. The cyclic overlap of bonding orbitals results in anti-aromaticity destabilization. The C-C bonds are formed by overlap of p-orbitals, so the 90 angle results in large angle strain. all the carbons are sp2 hybridized, so there is considerable angle strain. Define the stereochemical relationship between the following two structures: are identica structure are enantiomers are meso compound are diasteroisomers
