- Statement: "Increasing strength of hydrogen bonding is ClHCl < NHCl < OHCl < FHF." - Explanation: The strength of hydrogen bonding depends on the size of the atom, electronegativity, and ease of donation of electron pairs. The order provided in the statement is correct as it reflects ...
There are two main forces involved with molecules: intramolecular forces (ionic attraction and covalent molecular bonding) and intermolecular forces (London dispersion/Van der Waal's attraction, dipole-dipole attraction, and hydrogen bonding). It is the intermolecular forces that influence the spatial ar...
a) London Dispersion b) Dipole-dipole c) Hydrogen Bonding Of the two compounds H2O and CCl4, which has the stronger intermolecular forces? Explain. Which of the following substances has the strongest intermolecular forces? a. HCl b. C8H18 c. CH3OH d. CH4 e. CO2 What is th...
- Example: Hydrogen chloride (HCl) and hydrogen bromide (HBr). 4. Characteristics of Dipole-Dipole Forces: - These forces are stronger than London dispersion forces because they involve permanent dipoles. - The strength of dipole-dipole interactions depends on the polarity of the molecules involved...
Cells were lysed in TNE-N (1% NP-40, 100 mM NaCl, 10 mM Tris-HCl, pH 7.5, and 1 mM EDTA) buffer. The protein concentration of cell lysate was measured by Bio-Rad Protein assay kit (Bio-Rad). Cell lysates were boiled for 10 min with 4x NuPAGE LDS sample buffer (Life...
Mitochondria were incubated in either isotonic buffer (10 mM Tris HCl, pH 6.7, 0.15 mM MgCl2, 0.25 mM sucrose, 1 mM DTT and protease inhibitor cocktail (Sigma, 5892970001)) or H2O (extreme hypotonic condition) for 5 min, followed by centrifugation (10,000g for 10 min) to separate the ...
Following freeze-drying, the concentration of immobilized Lactobacillus plantarum decreased to 798 log CFU/g, and further exposure to simulated gastrointestinal conditions (HCl pH 20 and 0.3% bile salt) reduced the count to 294 log CFU/g; conversely, no non-immobilized culture remained detectable. ...
Which substances exhibit only london (dispersion) forces? HCl He H_2O How do molecules attract one another? Explain using two water molecules as an example. Define the term hydrophilic. What is the application of the fluid friction apparatus?
Which compound has the highest boiling point? HF, HI, HBr, HCl, or F2? Which chemical element has the highest boiling point? What is the name of the covalent compound CCl4? Which compound in each pair has the higher boiling point?
