Introduction/Aims:
We designed an interactive web module to improve medical student competence in screening and interventions for hazardous drinking. We assessed its impact on performance with a standardized patient (SP) vs. traditional lecture.
Setting:
First year medical school curriculum.
Program Description:
The web module included pre/posttests, Flash(c), and text didactics. It centered on videos of two alcohol cases, each contrasting a novice with an experienced physician interviewer. The learner free-text critiqued each clip then reviewed expert analysis.
Program Evaluation:
First year medical students conveniently assigned to voluntarily complete a web module (N = 82) or lecture (N = 81) were rated by a SP in a later alcohol case. Participation trended higher (82% vs. 72%, p < .07) among web students, with an additional 4 lecture-assigned students crossing to the web module. The web group had higher mean scores on scales of individual components of brief intervention (assessment and decisional balance) and a brief intervention composite score (1-13 pt.; 9 vs. 7.8, p < .02) and self-reported as better prepared for the SP case.
Conclusions:
A web module for alcohol use interview skills reached a greater proportion of voluntary learners and was associated with equivalent overall performance scores and higher brief intervention skills scores on a standardized patient encounter.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...

Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
