At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has
(1) stronger covalent bonds
(2) stronger intermolecular forces
(3) weaker covalent bonds
(4) weaker intermolecular forces

The physical state of a substance (solid, liquid or gas) is dependent on the forces keeping the molecules of the substance together, known as intermolecular forces. The stronger the intermolecular forces, the closer the molecules will be and they would tend towards solid behavior. Weaker intermolecular forces mean more gas-like behavior. Therefore, the answer is (2), bromine has stronger intermolecular forces.

2positives of biotechnology: 1. plants have become more resistant to viruses and other communicable pests.2. with the of biotechnology, we have been able to produce better tasting fruits as well as vegetables.2 negatives of biotechnology: 1. biotechnology poses a number of environmental threats. genetically modifies crops often infect monarch butterflies and other insect species.2. viruses could combine with crops.
