Is CH3Cl polar or nonpolar? Of these four molecules: 1-butanol, 2-butanol, 2-methyl-1-propanol, and 2-methyl-2-propanol, which has the highest melting point and which has the lowest melting point? Why? Justify your answer using molecular explanations. ...
Organic solvents like benzene, ether, and chloroform are neither protic nor strongly polar. What effect would you expect these solvents to have on the reactivity of a nucleophile in SN2 reactions? What alcohol is an isomer of dimethyl ether? *Express answer as a condensed structur...
1E), suggesting that the polar cell domain is intact at the supernumerary poles in branched ΔibaG cells. FIG S1. 10.1128/mBio.00790-19.1 Comparison of secondary structures and amino acid sequences of BolA and IbaG in E. coli and V. cholerae. (A to C) ClustalW alignment of predicted...
DAG was migrated with diethylether/heptane/acetic acid (75:25:1 v:v:v) mixture, the plates were dried and stained with 0.003% Coomassie brilliant blue in 30% methanol and 10 mM sodium chloride for 30 min. The plates were destained for 5 min in dye-free solution and the band density ...

(2005). The acidic fractions were eluted using 1% formic acid in diethyl ether on a pre-acidified column. The acidic fraction was subsequently methylated at 60 °C for 1 h using 1 ml of 14% BF3in MeOH. Fatty acid methyl esters were extracted from the solution by agitating it four ...
- C. Dipole-induced dipole interaction: This occurs when a polar molecule induces a dipole in a nonpolar molecule. This is not applicable for hydrogen bonding. - D. Induced-dipole-induced-dipole interaction: This occurs between two nonpolar molecules that induce temporary dipoles in each other. ...
Apolar lipid extract was separated by 1D TLC in 9:1 ratio of petroleum ether:diethyl ether and detected with 10% phos- phomolybdic acid in ethanol. Polar lipid extract was separated by 2D TLC in the presence of 60:30:6 ratio of chloroform: methanol: water for 1st direction and 40:25:...
The dried cells (4.43 g) were extracted with mixtures of chloroform, methanol and diethyl ether to yield crude lipid extracts (320 mg) as previously reported56,57. The extracts were separated to purify GlcADG (17.8 mg) using the same protocol described above for the purification of UK1. MS...
